Although you can specify that the clients be downloaded from the local appliance, Micro Focus recommends hosting the Filr desktop applications on a separate web server, as documented in Section 7.0, Hosting Desktop Application Installation Files on a Separate Server.
For example, if the server host name is myserver.example.com, then a URL similar to the following would need to be set in the Web Administration Console (port 8443). Click Desktop Application in the left frame.
The Filr desktop applications can also be hosted on Filr appliances, as documented in Section 7.0, Hosting Desktop Application Installation Files on a Separate Server, provided that the appliances are not fronted by an L4 or L10 switch.
For more information on configuring the desktop applications, see Desktop Access—Default Settings
in the Filr 3.4.1: Administrative UI Reference.
