CommuniGate Pro
Version 5.1

File Storage

CommuniGate Pro Accounts contain a File Storage - a set of HTML, JPEG, and other files. This file set is also known as a personal Web site.
The CommuniGate Pro HTTP module can be used to retrieve files from these sites.

The CommuniGate Pro FTP module can be used to retrieve and update File Storage files, and the CommuniGate Pro TFTP module can be used to download File Storage files.

The CLI API can be used to manage the Account File Storage.

Only the Account owner or an Administrator can modify Account File Storage.

A File Storage can contain nested folders (file directories).

If the Account and its Domain have the WebSite Service enabled, anybody can retrieve Account File Storage files using any HTTP browser, FTP, or TFTP client.

If a File Storage file is located inside the private "folder" (directory), the browser (HTTP), FTP, or TFTP user needs to authenticate as the Account owner or as an Administrator to access that file.

The total number of files and folders and the total size of all File Storage files is limited with the Account Settings.

File Storage can also be used:

HTTP Access to File Storage

CommuniGate Pro allows each user to be presented on the World Wide Web with a personal Web site. The URL for the accountname@domainname Account File Storage is:
<http://domainname:port/~accountname>   where the port is the
WebUser port.
For example, the account has a personal Web site at:

Personal Web sites use the same HTTP port as the WebUser Interface (the port 8100 by default).

In addition to the ~ prefix, an alternative prefix can be specified in the Domain Settings. The alternative prefix can be an empty string.

All Routing Rules discussed in the Access section apply to the personal Web site URLs, so Account and Domain aliases can be used in the personal Web site URLs.

Personal Web sites can be accessed without a prefix, using just the server part of the URL string. When the CommuniGate Pro server receives an HTTP connection on the its WebUser port, it uses the special Domain Routing procedure.

If the domain name has a DNS A-record pointing to the IP address of the CommuniGate Pro server, and the CommuniGate Pro Router has the following record:
<> =
and the Account userA exists in the CommuniGate Pro Domain domainB, then the URL can be used to access the personal Web site (File Storage) of the Account.

File Storage must not contain any index.wssp file. This name is reserved for the File Storage Management forms.

The home (default) page of a personal Web Site should have the default.html name. This means that when the file name is not specified explicitly, the default.html name is assumed. If a File Storage has folders (subdirectories), then the request with the http://server:port/prefix user/folder/ URL retrieves the default.html file from that subdirectory.

The name of the default page is specified as an Account Setting and it can be modified on the per-Account basis.

Private Folder

An Account File Storage can contain a folder with the name private.
Files in that folder are available only to the Account owner and Administrators with the CanAccessWebSites Domain Access right.

The private folder can be used as a repository for any type of documents - the user can access them from anywhere, using any browser, FTP, or TFTP client.

HTML-based Management

Users can manage their Account File Storage using any browser. There are two methods to access the File Storage adminstration pages:

Server administrators with the All Domains and Accounts Access Right and Domain administrators with the CanAccessWebSites access right can access other Accounts' File Storage.
They can use the same URL, opening the Index.wssp file, but they should provide their own Account names and passwords.

Server and Domain administrators can access File Storage of any Account using the WebAdmin Interface: the Account management pages have the Files link in their navigation panels.

All management methods use similar HTML pages for File Storage administration:

  Name Size Modified
This Folder:2488 

Click the Browse button and select a file you want to upload to the File Storage. Click the Upload File button to upload the file. Its name should appear in the list.

Select the checkboxes to mark the files and/or folders you want to remove from the File Storage and click the Delete Marked button. The selected files will be removed.

Type in a name and click the Create Folder button to create a folder (sub-directory) in the File Storage.

Select exactly one checkbox to mark the file or folder you want to rename, and enter a new name for it in the field next to the Rename Marked button. Click the Rename Marked button to rename the selected file or folder.

Click the file name link to open the file. Click the folder name link to open the subdirectory. When a subdirectory is opened, its name is displayed on the top of the file list. Click the UP link to open the parent subdirectory.

The This Folder line displays the total number of files and folders, and the total size of all files in the opened folder. The Totals line displays the total number of files and folders, and the total size of all files in the File Storage. The limits line displays the specified maxmimum number of files and folders and the specified maxmimum total file size for this File Storage.

HTTP-based Management

File Storage data can be modified using the HTTP 1.1 PUT, DELETE, and MOVE methods. Some HTML design tools can use these methods to upload files to the server.

These HTTP requests should contain the Authentication information: the Account name of the File Storage owner or the Account name of a Server/Domain Administrator, and the password for that Account.

FTP-based Management

File Storage data can be modified using the CommuniGate Pro FTP module. When an Account user connects to the FTP module, the FTP "root directory" as well as the "current directory" are set to the topmost directory of the Account File Storage.

Special files

Certain File Storage files have special meanings.

This file is retrieved via HTTP when no file name is specified in the URL: http://server:port/~username/ or http://server:port/~username is equivalent to http://server:port/~username/default.html.
The same is true for all File Storage subfolders: http://server:port/~username/subfolder/ is the same as http://server:port/~username/subfolder/default.html
This default file name can be changed on the per-Account basis, by modifying the Account Settings.
This text file contains the user Free/Busy information. When the Account Main Calendar mailbox is modified with the CommuniGate Pro MAPI module, XIMSS interface, or with the WebUser Interface module, the file is deleted.
When this file is being accessed and it does not exist, the Server opens the Account, opens its Main Calendar mailbox, builds the Free/Busy information, and stores the information in the freebusy.vfb file.

If the Free/Busy information cannot be built (for example, if no Main Calendar mailbox exists in the Account), the HTTP module generates an empty Free/Busy dataset and sends it to the client.

These files contain meta-information about the any_name files. For example, the Betty.jpeg.meta file contains meta-information about the Betty.jpeg photo file, such as the location where the photo was taken, comments, etc.
When a File Storage file is being renamed or removed, its meta-file is automatically renamed or removed with it.
The meta-file should be a text file in the XML format.

Virtual Files

Virtual files are the names that can be used in the personal Web site URLs. They do not specify actual files in the File Storage, but they can be used to retrieve certain information.

This name is used for HTML-based File Storage management. Access to this resource requires authentication.
This name is used to retrieve formated Free/Busy information. The actual data is retrieved from the freebusy.vfb file (see above).
