WS_FTP Server Web Transfer Client Notes

Note: WS_FTP Web Server is no longer supported
  • When using the Firefox browser on an Apple Mac computer, note that the browser does not implement the proper Tab order on the Login page (login.aspx).
  • Both WS_FTP Server Web Transfer Client and Internet Information Services (IIS) have limits on the size of file that can be uploaded. When a user tries to upload a file that is larger than the Web Transfer Client's maximum upload size, the Web Transfer Client displays an error message at the top of the main page (Transfer.aspx).

    If the upload exceeds the IIS maximum upload size, the browser displays a page error and does not return to the Web Transfer Client page.

    Though we cannot change the browser behavior, both of these upload values can be set in the web.config. The default path is:

    • 32-bit: C:\Program Files\Progress\WS_FTP Server\WebClients\ThinClient
    • 64-bit: C:\Program Files (x86)\Progress\WS_FTP Server\WebClients\ThinClient
Note: When you save changes to the Web.config file, all active WS_FTP Server Web Transfer Client sessions will be reset, which means that any user logged on via the Web Transfer Client will be returned to the Logon page, and will have to log on again.
  • Web Transfer Client maximum upload size is set in the <appSettings> section:

    <add key="MaxUploadSize" value="50"/>

    The value is in MB, so the maximum upload size for the Web Transfer Client is 50 MB.

  • IIS maximum upload size is set in the <httpRuntime> section:

    <httpRuntime maxRequestLength="2097151"/>

    The value is in KB, so the maximum upload size is GB.

The IIS limit can also be set in other locations, namely machine.config, and IIS metabase, though we recommend using the web.config settings.

  • Be aware that browser security settings can influence the download count shown in logs. For example, if the Internet Explorer security setting 'Automatic prompting for file downloads' is not enabled, when Web Transfer Client user selects to download a file, Internet Explorer will pop up the following message and it will add 1 to the download count:

    'To help protect your security, IE blocked this site from downloading files to your computer. Click here for options.'
