Specifying Extensions for Files That the Redirect Server Accepts (C-Web Interface)
If you do not specify the types of files that the redirect server accepts, the redirect server accepts all file types. You can identify file types by specifying the file extensions for the files that the redirect server is to accept.
To specify the extensions for the types of files accepted by the redirect server:
Click Configure>Redirect Server.
The Redirect Server pane appears.
To enable or disable checking file extensions, clear or select the Check File Extensions box as described in the Help Text in the main pane.
