5 Using WebShare

This chapter explains step by step how to log on to the WebShare File Server, how to select a sharepoint and how to use the buttons in the sharepoint toolbar.

5.1 WebShare File Server login

Launch a browser and enter the WebShare Web Server address using port 2009, e.g.: http://hostname.company.com:2009

In the WebShare File Server field enter the name of the server you want to connect to (or just accept the provided server name), select the desired language from the Language pop-up menu, and click on the Continue button (Fig. 5.1).

Note:

The login form must be completed within 2 minutes. Otherwise a time-out error will occur. In addition, the user has only 3 trials to log in.

You may also preselect the WebShare File Server via the URL parameters “wshost” and “autoforward”:

http://<domain>:<port>/?wshost=<a fileserver name>

The file server name is set to the value specified by the “wshost” parameter in the WebShare File Server login field.

http://<domain>:<port>/?wshost=<a_fileserver_name>&autoforward

This URL pastes the WebShare File Server name, which is handed over by “wshost”, into the WebShare File Server login field and proceeds with Continue.

For this to work, JavaScript must be activated in your browser. If JavaScript is not active, only the WebShare File Server is pasted.

In the upcoming window fill in the User Name and Password fields and click on the Login button (Fig. 5.2).

Note:

The password field should have the annotation Crypted RSA... in order to ensure a secure password transfer. If it shows Cleartext, enable JavaScript in your browser to avoid insecure clear text password transfer. See also JavaScript in 9.1.1 “WebShare Web Server”.

If you do not already have a user name and password, use the Register as a New User link (if enabled) to enter user data in order to receive a WebShare account. If you already have a WebShare user name, but forgot your password, use the Forgot Password? link (if enabled) to request a new login password.

After a successful login, the “Home” page appears, which allows the selection of a WebShare sharepoint from the Sharepoint Name list (Fig. 5.3).

To open the desired WebShare sharepoint (Fig. 5.4), click on the corresponding link.

You can also open a new window for browsing by clicking on the New link in the “Window” column. Note that you can only have one window open for each sharepoint per login.

If you logout from one window, all other windows belonging to the same session will also be disconnected. When you then click on a link in one of these windows, you will be redirected to a “Session time out” error page with the message: Your session has been terminated. Use the link Click here to log in again.

5.2 WebShare access keys

WebShare supports access key navigation that facilitates many user operations, which would have been done via mouse clicks otherwise.

Access keys are enabled in a different way with different browsers. So please check your browser documentation. Access keys that are marked with an * are used without modifier key.

5.3 Work in a sharepoint

This chapter describes how to work in a WebShare sharepoint.

For faster access to commands on single files, a contextual menu has been added to the file browser. It provides the most used commands (Download, Preview, Copy, Duplicate, Delete, Rename, Permissions, Open) without the need to select the file and choose the command from the menu. Open allows opening PDF, movies, Flash, Photoshop (“.psb” and “.psd”, if supported by the browser, e.g. Safari) and other file types directly in the web browser.

To open the menu, click on the icon, which appears when hoovering over the file name. Note that a current selection will be reset when using the contextual menu.

Note:

JavaScript needs to be activated in the web browser to use features such as the contextual menu or the automatical local time zone adjustment in the “Date” column.

5.3.1 The WebShare toolbar

In the following, the icons in the toolbar (Fig. 5.5) are described. Underneath the toolbar the directory level in the sharepoint is shown. You may click on a subdirectory to jump to that level. A click on the folder symbol allows you to jump one level up or back from the preview mode.

Note:

If items in the toolbar appear grayed out then you do not have sufficient permissions (see 4.4 “Sharepoint Administration”). Ask the Administrator.

Opens the list of all sharepoints that are available to the logged-in user.

A click on this button reloads the page from the WebShare File Server. This may become necessary e.g. after one or more files have been uploaded to a WebShare sharepoint or have been modified by other users, in order to display them correctly in the sharepoint window.

Opens the WebShare “Administration” page. See Fig. 4.2 in 4 “Administration”.

This toolbar item contains a submenu with the following items:

Create Dir
Create a new directory in the sharepoint.

Permissions
View and change file or folder permissions. This feature is of great value, to allow setting permissions so that other users can be allowed or denied access to files and folders. See also 5.3.3 “Note on file access permissions”.

Note:

Changing permissions is only allowed if Allow Rename is activated (see Allow Rename in 4.4 “Sharepoint Administration”).

Rename
Rename a marked file or directory in the sharepoint.

Duplicate
Duplicate one or more marked files or directories into the same directory. Duplicated files will have “copy”, “copy 1”, “copy 2”, etc. appended to their name, before the suffix.

Delete
Delete the marked files from the sharepoint. As a means of security and to avoid inadvertent deletion, you will be asked to confirm the deletion by clicking on the Remove Selected Items button or Cancel to remove all checkmarks.

Preview
Show a preview of the marked item(s); if no item has been checked all documents are opened in preview mode. See also 5.4 “Image and document previews”.

Search
Search for files and folders within the sharepoint. In the example below (Fig. 5.6) a full-text search for files with the terms “job”, “titles”, and “print” is done. You may filter the search by the modification date with the pop-up menu Modified, and also limit the number of hits with the Max. Results pop-up menu. If the Limit Search To Current Folder option is checked, the search is limited to the folder from which the search was started. Searches are case-insensitive.

After clicking on the Search Files button all hits are listed in the Search Result section (Fig. 5.7). You may directly go to each hit by either using the arrow buttons, by clicking on the link underneath each hit or by using the access key P and N (see 5.2 “WebShare access keys”). All described ways have in common that the file is selected automatically. However, clicking on the file name itself will open the file in preview mode.

The File Search as well as the Search Result section can be hidden by clicking on the arrows in the left upper corner of the respective section or by clicking the caption “Search Dialog” and “Search Result” respectively. Another click will show them again.

A click on the Cancel button will close the WebShare file search section.

More details on the HELIOS Spotlight search, and search options, are covered in the HELIOS Index Server manual, in the chapters “Simple Spotlight syntax” and “Advanced Spotlight syntax”.

When moving the cursor over the Spotlight search field in the WebShare toolbar or the “Search Dialog” search field (Spotlight search must be selected from the pop-up menu), a link to a Spotlight search help pop-up window becomes visible (Fig. 5.8).

The link Show all indexed attributes, at the bottom of the “Spotlight Help” window, displays all attributes indexed by the indexer modules (see HELIOS Index Server manual). A click on an attribute inserts it in the search field.

Label >
Mac operating systems up to Mac OS 9.x, and then again from Mac OS X 10.3 on, allow assigning color labels to files and folders. Files and folders can be “marked” for their importance or priority. HELIOS WebShare offers a similar functionality in this submenu.

Note:

HELIOS Admin allows defining color labels in its Settings > Color Labels menu (see HELIOS Base manual).

Set View >
Change the view of the directory listing, e.g. add or extend column types, and display the listing in a set of 4 predefined modes (Default, Smart, Extended, and Small). The smart view option displays a preview thumbnail of image files instead of the file type thumbnail. Note that only the extended view option includes the UNIX file permissions. This is a convenient means to see who is allowed access to specific files and folders. These permissions can be changed by using the Permissions option in the pop-up menu (see above). The options Hide Comments and Show Comments allow hiding and unhiding file comments.

You may also browse the files in a gallery view mode rather than in a list. The gallery view mode can be enabled in two ways:

From the sharepoint toolbar select File > Set View > Gallery.

Or just click on the gallery icon in the toolbar, adjacent to the sharepoint path information.

This toolbar item contains a submenu with the following items:

Select All
Mark all checkbox items in a sharepoint at the same time. Clicking on this button again will unmark all items.

Copy
Copy one or more selected files or directories into the WebShare internal clipboard for later pasting.

Paste
Paste one or more previously copied files or directories into the currently opened sharepoint directory path. Existing files are not overwritten, but will have “dup”, “dup 1”, “dup 2”, etc. appended to their name, before the suffix.

Note:

The difference between copying/pasting a selection and duplicating is that copied items can be pasted into different sharepoints or different directories. However, duplication is only possible within the same sharepoint, i.e. directory.

Note:

Copy, Move and Paste are allowed according to your server file and folder permissions. The setting of the Always Allow Reading and Always Allow Read/Write checkboxes (see 4.4 “Sharepoint Administration”) has no influence on that.

Move
Move one or more previously copied files or directories into the currently opened sharepoint directory path. The behavior is the same as if using Paste, with the exception that the source files or directories are deleted.

Mail
WebShare provides a front-end for the HELIOS mail tool, which allows sending e-mails directly from within WebShare. Selected files and folders will be listed in the mail body (Fig. 5.9).

This toolbar item contains a submenu with the following items:

Download
Download one or more files or folders that have been marked to the local disk. These will be transferred to the client in a Zip file named “download.<date>.zip”. For example, the file “Cafeteria.tif” will be contained in a Zip file named “download.09-06-15.zip” after being downloaded from a WebShare sharepoint on June 15, 2009.

Important:

Empty directories are not included in the downloaded Zip file. Color labels, comments, and other attributes are preserved for downloaded files, but not for folders.

After extraction, each download folder includes the file “DownloadLog.txt”, which contains a list of successfully downloaded items, and for any omitted items a short description why they were omitted.

Upload
Open the “Upload” window (Fig. 5.10) to select the file to upload.

After selecting the file, it can be uploaded using the Start Upload button. For best performance, and to upload multiple files, it is recommended that a Zip archive be created to upload. This is easily done using the Mac OS X Finder Create Archive of “<file>” functionality. Windows clients (XP or later) can use the Zip archiving and extracting capability built into the Windows Explorer via the Send To > Compressed (zipped) Folder context menu. By default, uploaded Zip archives are automatically extracted on the WebShare File Server (see 5.7.1 “Supported upload formats”).

Note:

If you wish to upload a Zip file to the sharepoint without automatic extration, deactivate the Extract Archive checkbox. If you wish to extend this behavior to the whole WebShare server, read the instructions below.

After clicking the Start Upload button the file is uploaded to the selected sharepoint (Fig. 5.12, compare with Fig. 5.4). When the upload is done, details in terms of file size, upload performance, etc. are displayed (Fig. 5.11).

If the name of a file to be uploaded already exists in the destination folder, the uploaded file will have “dup”, “dup 1”, etc. appended to its name, before the suffix. This refers only to a duplicate name, not to the actual file content, which may or may not be the same.

If a folder does already exist with the same name as an uploaded folder, the two folders are merged. Duplicate file names within this folder then follow the rule explained above (“dup” extension to file name).

If you wish to upload Zip archives without automatic extraction by default, you must edit the “wsupload.pl” script:

Copy “HELIOSDIR/etc/webshare/wsupload.pl” to “HELIOSDIR/​var/​webshare/​wsupload.pl” and change the line:

@unzipOpts = ("-u", "-m", $mimetype, "-o", "$fname", 
"-n", "$wsmv", "-C", "$dir");

to

@unzipOpts = ("-u", "-m", "application/octet-stream", 
"-o", "$fname", "-n", "$wsmv", "-C", "$dir");

Note:

If ImageServer and WebShare are installed on the same host, the OPI server will by default create layouts of uploaded files. You can switch this behavior off according to the instructions given in the HELIOS ImageServer manual.

Open
Open PDF documents, movies, Flash and other file types directly in the web browser. For this to work, the file must be checked in the “Select” column. Note that JavaScript must be activated in the used browser to use this feature.

This toolbar item makes action scripts available that are stored in “var/​settings/​WebShare/​Actions”. Corresponding icons must be named “<action>.png” and copied to “var/​settings/​WebShare/​Brandings/​<branding>/​actions”. Fig. 5.13 shows an example for two action scripts, “wsll.pl” and “wssendmsg.pl”, including their corresponding icon.

Important:

The Actions > item in the WebShare toolbar is only available when scripts are stored in “var/​settings/​WebShare/​Actions”!

5.3.2 Add file comments

You may add file comments, which are also available when accessing that file from EtherShare or PCShare, to any file in a WebShare sharepoint. These comments are restricted to 199 bytes.

In the sharepoint file browser click on the button pertinent to the item to add a comment.

To read or modify an already existing comment click on the button.

5.3.3 Note on file access permissions

When setting permissions on sharepoints and files, it is important to keep in mind the following file system rules that affect who can rename and delete files and folders.

The write (“w”) permission for a file controls only the changing of the file content. This permission has no control over the renaming or deleting of that file.

The write (“w”) permission for folders controls the changing of folder content, i.e. files and subfolders within that folder. The permissions set on a folder control the changing of file names and the adding or deleting of files within that folder.

Hence, if you wish to create a folder where users can read and modify files, the folder would need read/write permissions. However, if you wish to save a reference file to that folder, and do not want anyone to be able to rename or delete it, then the only way to do so is to save it into a different folder (or a subfolder), which has read-only permissions. Generally, when a WebShare user attempts to perform an action that is not allowed, either no action occurs or an explanatory error message is displayed.

Note:

In EtherShare volumes, changed folder permissions will also change permissions of all files in this folder in order to be compatible with AFP 2.2, which only supports folder permissions. However, changing file permissions only affects the files.

In addition to users who have permissions for a file or folder as described above, “root” and members of the groups “SysAdm” and “WSAdm” are also allowed to make modifications on file and folder permissions in WebShare (even if the file access permissions would not otherwise allow them to do so). Fig. 5.14 shows permissions for 2 folders and 2 files. The folder “PUBLIC” as well as the file “public.txt” are accessible by everyone. The permissions are:

drwxrwsrwx for the folder and -rw-rw-rw- for the file.

The folder “PRIVATE” as well as the file “private.txt” are only accessible by the owner (“root”), its group (“daemon”). The permissions are:

drwxrws--x for the folder and -rw-rw---- for the file.

Note:

Check with your UNIX server administrator for questions about permissions.

5.3.4 Logout

Clicking the Logout button will close all connections for that user, abort any downloads in progress and exit to the WebShare “Logged Out” page (Fig. 5.15).

If user closes the browser without logging out or the user has been idle for a time, i.e. no web activity has occurred, the session will automatically be closed, after the idle time period specified by the WOSessionTimeOut preference (see 6.5 “Preferences”).

The Click here to enter again link leads directly to the login window (Fig. 5.1).

5.4 Image and document previews

If the Allow Preview option is enabled, WebShare can generate bitmap previews when a user clicks on an image or document.

WebShare automatically detects all supported image and document types. The previews are generated by the “wspreview.pl” script which makes use of the image conversion program “wsconvert”. All previews will be generated as either JPEG or PNG files in an RGB or grayscale color space.

This script can be modified to change the default behavior. Or it can be used as a template for custom “action scripts”, e.g. to create previews with specific ICC profiles.

The following image and document input formats are supported:

TIFF, EPSF, DCS-1, DCS-2, Scitex-CT, JPEG, JPEG 2000, JBIG2, PICT, Photoshop, BMP, PDF, PNG, XPV, and all common RAW camera images.

WebShare can display previews of multiple-page PDF documents (also in facing pages view, with or without page break).

Note:

Password-protected PDF files cannot be previewed.

If ImageServer is installed, previews of QuarkXPress and Adobe InDesign documents (Mac and Windows) are supported. For such previews it is necessary to install the HELIOS Preview extension for QuarkXPress or InDesign. The extensions automatically save an “.xpv” file containing the document preview together upon each QuarkXPress or InDesign document save. A WebShare user can click on this “.xpv” file to view the document previews of each page.

WebShare generates PNG previews for the following formats:

• PDF

• QuarkXPress & InDesign documents (“.xpv”)

• All images containing a clipping path

• 1 bit images (black/white)

WebShare generates JPEG previews for the following formats:

• All grayscale and color images without a clipping path

All previews and proofs, once generated, will be stored in a customizable caching area to allow the reuse of existing rendered previews by other users.

It is possible to customize the preview generation by using different ImageServer parameters in the “wspreview.pl” script, e.g. to specify a different ICC profile for the RGB color space that is used for the previews.

The following resolutions are supported by default:

• Zoom 1: 256 pixel (default after clicking on images; image width is scaled to 256 pixel)

• Zoom 2: 512 pixel

• Zoom 3: 768 pixel

• Zoom 4: 1024 pixel

Additional preview resolutions can be specified as pixel or dpi values on the “Server Preferences” administration page. The customizable resolutions are selectable in the pop-up menu. The preview resolutions should be limited to avoid very large preview images which may take very long to download and display within the browser. Zoom 1 to Zoom 4 are defined in the “Branding Editor > Branding Name > Preview Resolutions 1-4” preference.

Note:

If JavaScript is not enabled, clicking the Go button will start generating the preview specified in the pop-up menu.

5.4.1 Preview of images and single document pages

WebShare allows previewing images and supported document formats (see 5.4 “Image and document previews”). If this feature is enabled for a sharepoint, then file names will appear as links.

To view an image or document, click on the file name or select one or more files and click the File > Preview toolbar button.

If multiple items have been marked for preview in the directory listing, the first preview is displayed, and the other(s) can be selected from a pop-up menu or via the “next” and “previous” arrow icons (Fig. 5.16). A checkbox adjacent to the pop-up menu allows unselecting images in the directory listing (Fig. 5.12).

Previews can be scaled in resolution and dimensions via the magnifying glass icons or the dpi/pixel pop-up menu (Fig. 5.16). The dimensions and resolutions available in the pop-up menu (and in the Set View > button from the toolbar) can be specified in the Preview Resolutions (pixel or dpi) field of the WebShare “Server Preferences” page. The magnifying glass icons have fixed resolutions which can be defined per branding in the Branding Editor in the “Zoom 1-4” preference in chapter 4.6.1 “Create and configure brandings”). The default values are 256, 512, 768, and 1024 pixels. If you have specified monitor width values in the Monitor Size Information section in “My User Preferences”, the entry 100% is available in the Set View > Zoom menu or in the resolution pop-up menu, to display the preview images in their original size.

The Rotate > and Flip > toolbar icons allow transforming the preview according to the action selected in the corresponding submenu. The selected view settings (zoom, rotate, flip, info) are maintained for subsequent previews.

Set View > Show/Hide Image Info allows controlling whether basic image information is displayed along with each image.

5.4.2 “Color Info” and “Annotations”

Important:

For the “Color Info” and “Annotations” features, HELIOS PrintPreview must be installed and licensed!

The “Color Info” and “Annotations” dialogs cannot be used simultaneously!

Set View > Color Info is similar to the Photoshop color info and shows the individual primary color and spot color values used in the selected area (Fig. 5.17).

To obtain color information, open the color info window by selecting Set View > Color Info and click on the preview or proof image.

Note:

Color information for PDF documents is only available in proof mode and with a selected simulation profile.

The color values can be displayed in bit or percent values. The icon in the title bar can be used to toggle between these display modes. When retrieving color information of CMYK images, the TAC (Total Area Coverage) is also displayed in addition to the process color values.

To clear the list of color value entries, click the icon in the title bar.

Every click on the preview or proof image will leave a numbered marker which belongs to a list entry of the same number. If you hover over a list entry the corresponding marker will be animated, a click on a list entry scrolls the corresponding marker into view. A click on an image marker highlights the corresponding list entry and scrolls it into view. The “Color Info” dialog can be dragged by clicking on the title bar and resized by clicking on the lower right corner and dragging the window to the required size.

Note:

If color information for high-resolution image are retrieved while the preview resolution is relatively low, it can happen that the displayed results do not match the actual values. In this case the interpolation of the position where you have clicked to is to blame.

Note:

On the preview page the color info does not work for PDF documents. In the proof window the color info does only work for PDF documents if an entry from the ICC Proof Simulation pop-up menu is selected.

Set View > Annotations opens a dialog window, which allows attaching annotations to all file formats that can be previewed with WebShare (see 5.4 “Image and document previews”). It tracks document versions and allows signing off ready-to-go documents (Fig. 5.18).

Note:

JavaScript must be activated in your web browser to enable the annotations feature!

The annotations feature is not supported by Internet Explorer 6. Internet Explorer 7 and newer however do support this feature.

In order to make the annotations feature available for the current sharepoint, the Allow Annotations checkbox must be activated (see 4.4 “Sharepoint Administration”).

A discussion is opened by clicking on the icon in the left upper corner of the annotations dialog, and marking a point or a rectangle area in the document, which starts a new reviewing thread. A rectangle area marker allows selecting the marker color from a color picker and its opacity. From the pop-up menu Status, each user can specify within the annotation thread, if they agree or reject the issue, or leave everything as is. The next user can reply to an annotation by clicking the Reply button underneath the entry to which they wish to answer and set a new thread discussion status. If a discussion thread already exists, the overall status is displayed adjacent to the file information in the WebShare preview window (see Fig. 5.18 below).

After all threads of an document are answered in an accepted state, the document turns into final. Multiple document versions and multiple threads are supported.

An already existing discussion can also be opened by clicking the overall status icon or by clicking on the desired “<file name>.annotation” entry in the WebShare file browser.

The whole discussion is stored in a look-aside XML file, which stays next to the document. The (AnnotationPrefix) preference allows hiding the XML file or storing it in a directory. The XML format allows parsing the annotation records or automatically generating annotation files.

This also addresses all requirements to collaborate within a remote proofing workflow. Especially the multiple-version document support allows keeping the entire history and differentiate between versions. The annotation capability works for the WebShare document preview and proofing window.

WebShare annotations can be printed out using the WebShare print function (), see 5.4.5 “Preview/proof print settings”. The first page will contain the image with its marks, the following pages will show the comments.

5.4.3 Previews of multiple-page documents

If you open a multiple-page document, the toolbar is extended to offer more functions (Fig. 5.19):

You may navigate through the document by entering the desired page number and pressing the ENTER key or the “Refresh” button of the toolbar, or you can flip the pages forward and backward.

In addition, you can add or remove rows and columns for previewing multiple-page documents. This can also be done in the Set View > Rows/Cols > toolbar menu. Presets are available in the View Presets > submenu; 2x2, 2x4, and 4x4 rows/columns.

Note:

The maximum number of concurrently displayed preview images is 300.

Set View > Options > makes two more preview options for multiple pages available:

Facing Pages
The pages of a document face each other, with the even numbered pages being always on the left and odd numbered pages on the right (Fig. 5.20).

Note:

Multiple-page documents are considered as books if Facing Pages is selected. Therefore the first page of a document is always displayed single.

Page Breaks
The gap between facing pages is removed if Page Breaks is selected (compare Fig. 5.20 and Fig. 5.21).

5.4.4 Banner and trailer files per document

To display file-related information in the file preview, WebShare searches the current directory for files with the same file name and a “.banner” or “.trailer” suffix, and displays the content of these files in the file preview. For example, the files “Cafeteria.tif.banner” and “Cafeteria.tif.trailer” will be displayed above/below the file preview of the file “Cafeteria.tif”. HTML content is allowed for these files.

5.4.5 Preview/proof print settings

A click on the Print toolbar icon allows specifying print settings prior to using the standard OS print dialog, when printing a preview or proof image (see Fig. 5.22).

The Paper Size pop-up menu allows choosing a pre-defined paper format from the list, or Custom... which opens the Extended Options dialog. Here you can specify custom values for the page dimension, and in addition define a scaling factor. The values that are specified are used for scaling and positioning only and it is important that they match those selected in the browser dialogs “Print” and “Page Setup”, respectively. The “Paper-Formats.txt” document, which is located in the “WebShare Public” sharepoint (“Proof-Templates” directory), contains all those paper formats that become available in the Paper Size pop-up menu.

Note:

If you check the Scale Images To Fit Page option, the choosen scaling factor may be overriden.

The Resolution pop-up menu allows selecting the resolution for printing the document:

Draft (150 dpi)
Good (240 dpi)
Excellent (300 dpi)
Super Fine (400 dpi)

Note:

By default, or if PrintPreview is not installed and licensed on the server, the resolution of the preview image is 150 dpi.

If the Print Annotations (PrintPreview required!) and Print Images options are checked, the first page will contain the image, the following pages will contain the annotations.

In proof mode, an additional checkbox, Print Image Info, becomes available. If this option is checked, all dialogs are included in the printout.

When printing multiple-page documents, the “Print Settings” dialog offers an additional section (Fig. 5.23) which allows specifying the printing range. Current view prints the page(s) displyed in the browser, or a range of pages when using the From and To fields. If you wish to print only those pages that contain images with annotations, use the Images With Annotations Only option.

For the print output of the preview, workstation-based color management (sRGB v4 ICC) is applied.

5.5 Remote Proofing

Together with HELIOS PrintPreview, WebShare allows remote soft proofs on the monitor and color-matched proof prints from the web browser.

The remote proofing feature is described in detail in the HELIOS PrintPreview manual.

5.6 My User Preferences

In Administration > My User Preferences personal user settings (Fig. 5.24) can be specified. The dialog allows the user to specify individual settings for downloading files, which may well override the settings specified by the administrator on the “User Administration” page.

With the Preferred View pop-up menu, the user can define their preferred initial file browser view. It offers: Default, Extended, and Small. The option Gallery is only available if the gallery view is activated (see Max. Gallery Resolution (4.1 “Server Preferences”).

The Download Encoding pop-up menu offers MacRoman, PC850, ISO8859-1, UTF8, MacIcelandic, EUC-KR, and SJIS encoding methods. In addition, OS Default uses the client OS default encoding, which was set by the administrator (see Fig. 4.3 in 4.1 “Server Preferences”).

With the Zip Streaming Format checkbox activated, the file download uses Zip streaming (instead of a standard Zip file download), which allows file compression on-the-fly, without creating any temporary files.

After changing your user preferences click on the Save User Preferences button. Otherwise your changes will get lost.

With the Save Default Settings button the admin user can save their personal settings as default settings for all other users. The settings are stored in “HELIOSDIR/var/run/WebShare_User_Settings/WSdefaults.settings”. The default settings are overridden by personal user settings.

Any custom JavaScript properties (see 7.2.1 “WSProperties”) and data entered in the “Monitor Size Information” section (properties starting with Default.screen.< ... >) will not be saved in the default user settings.

In addition, the “Change WebShare Password” section allows WebShare users to change their WebShare password on their own, without having administrative rights on the WebShare File Server. This is another means of security for Host Users who may not want to use their host user password over the internet. For example, a remote login to WebShare from an internet cafe bears the risk of a spyed host user password (e.g. keystroke logging spyware can capture a password as it is typed in, before the password is encrypted for transmission). If someone uses their host user name but a password that is only used with WebShare, the worst-case scenario would be a spyed WebShare login, with the host login not being affected. For more information on content security see also 9.1.10 “No content security”. Of course, Virtual Users can also change their password on their own in this configuration window.

Note:

Users which were assigned the “Cannot change Password” flag by the administrator cannot change their WebShare password on their own (see Create users in 4.2 “User Administration”).

Enter the old (existing) and the new password in the respective fields. To use the existing host user password again, Host Users leave the New Password field blank. For Virtual Users, any attempt to leave the New Password field blank will yield an error message. In this case the “original” WebShare password has to be entered again.

If Allow ICC Profiles per User is activated on the Server Preferences page (4.1 “Server Preferences”) the user can choose their default profiles by use of the Default Monitor Profile, Default Printer Profile, and Default Simulation Profile pop-up menus. The choosen profiles will automatically be selected in the Monitor ICC Profile and Printer ICC Profile pop-up menus in the WebShare proof window. Selecting a profile will switch the proofing mode from “Workstation color management” (profile is included in image, default behavior) to “Server color management” (profile is omitted). If no profiles are available on the server, the buttons Add Monitor Profile, Add Printer Profile, and Add Simulation Profile open an upload dialog.

Note:

As soon as a simulation profile has been added via the Add Simulation Profile button, all default simulation profiles defined in the “Server Preferences” page will disappear from the Default Simulation Profile pop-up menu.

With the Monitor Size Information link the visibility of the preferences Width (pixel) and Screen Width can be switched. With these properties the user may enter their monitor width in pixels in the Width (pixel) field and the width of the visible screen size in a selectable unit (mm, cm or inch) in the Screen Width field. If both preferences are set, the entry 100% becomes available in the Set View > Zoom menu of the file preview and proofing page to display images in its original size. If JavaScript is activated, the Detect button next to the Width (pixel) field can be used to automatically detect the pixel width.

WebShare will remember if a zoom level of 100% has been selected for the proof component, and will add this setting to the user settings file. When the component is opened again, the proof will be displayed at 100%, even with a new login. If another zoom level is selected, the setting is deleted from the user settings file.

If any global or user ICC profiles are available on the server, the user can have these profiles displayed in the Monitor Profile Administration, Printer Profile Administration, and Simulation Profile Administration sections. Profiles added by the user can be deleted by selecting the profiles and clicking the Remove Selection button. The Add Profile button opens a dialog to upload an ICC profile. Global profiles are displayed grayed-out and cannot be administered by the user. The profiles are stored in the “.Proof-Profiles/​<username>/​Monitor”, “.Proof-Profiles/​<username>/​Printer”, and “.Proof-Profiles/​<username>/​Simulation” folders of the root directory of the “WebShare Public” sharepoint.

Note:

Allow Preview has to be enabled for the “WebShare Public” sharepoint. The server preference Allow ICC Profiles per User has to be enabled and the “WebShare Public” sharepoint must be published for this feature.

5.7 WebShare file format support

5.7.1 Supported upload formats

• Uncompressed single file

• Windows XP (or newer) Explorer Zip files

• WinZip archives (8.1 has been tested)

• MacBinary encoded file

• Mac OS X 10.3 (or newer) Finder Zip archives

• Mac OS 8/9 DropZip (7.0.3) archives, including the MacBinary option

• Mac OS X DropZip 8.0.2 files (MacBinary)

We recommend using the Zip format for uploading. It offers the following benefits:

• Zip files have a high compression ratio

• Zip files can contain multiple files/folders

• DropZip files have support for Mac OS Resource/Finder information (MacBinary)

• Zip files preserve the file creation date

• Zip files preserve special characters in file names

5.7.2 Supported download formats

• Zip-compressed archives for UNIX and Windows clients

• Zip Streaming format supported by Windows XP (or newer), and by Mac, using Mac Finder Zip (Mac OS X 10.3 or newer)

5.8 Supported browsers

WebShare uses standard HTML web pages. Special browser plug-ins and Java are not needed. JavaScript is used to ease access to some features and to improve the overall appearence. However, WebShare generally works well without JavaScript being activated in the browser. WebShare has successfully been tested with many different browsers on Windows, Mac OS 9, Mac OS X and UNIX platforms. For power users, this chapter provides information about which browsers have intensively been tested by HELIOS, and some hints about possible problems.

Browsers for browsing and downloading files and folders

• Safari 3.0 and newer

• Safari* on Apple iPhone, iPad, iPod touch

• Firefox 3.0 and newer

• Internet Explorer 6 and newer

• Google Chrome 5.0 and newer

These above listed browsers have received more intensive testing and are considered to work perfectly with WebShare (Browsers marked with an * do not allow downloads). Again, many other browsers will just work fine with WebShare but have only received limited testing.

Automatic MacBinary upload support

All current browsers skip MacBinary data so that the document resource (e.g. preview picture, icon, document type) gets lost during the upload.

Solution:

 

Instead of uploading just files, generate Mac OS X Finder Zip archives (Mac OS X 10.3 or newer). Uploading the compressed Zip files will work with any browser.

Continuing browsing while uploading files

Some browsers do not accept additional requests while they are uploading files (refer to your browser documentation). A new browser window or using a different browser application allows logging in a second time and continuing with other tasks or monitoring the loading files. The disadvantage of the second login is that it will require one additional user session on the WebShare File Server.

Safari allows continuing while the upload is ongoing.

Saving a password in your browser/keychain

As WebShare crypts all passwords with a random number for every login, re-using the same old password does not work for a second time. Browsers may cache the user name and passwords and try to re-use it a second time, which fails with the WebShare login. HELIOS considers this a security feature of WebShare.

In case JavaScript is turned off the password is sent unchanged (in clear text) to the server, and the keychain/browser feature remembering this clear text passwords works again. We recommend to keep JavaScript active to allow encrypted passwords for the WebShare Server login.

Downloading progress bar does not match downloaded file size

When downloading files, the WebShare Zip streaming technology compresses files always on-the-fly during the download. The browser progress bar shows the uncompressed original size. However, the download size will differ due to the zipstream compression and additional changes on the server before the download is completed. The very last file in every download is called “DownloadLog.txt” which includes a list of all downloaded files and possible errors (file was not accessible anymore, no permission, etc.). If this file is included after unpacking the “download.zip” archive you can assume a complete download.

Do not use the back/forward buttons of your browser

WebShare keeps some state about the current directory, selected files, etc. Using the back button, the client will request a page and may use the selection of the previous page instead of the current one. This can lead to unpleasant results, e.g. if the selection was “delete files”. Only the “Home” window allows to open a separate window for each sharepoint. Do not use the back/forward buttons or the “Open Link in new Window” option of your browser. The central “Home” menu or selectable URLs in the file browser allow you to go back to different locations.
