Configuring HTTP and HTTPS Fallback

HTTP Fallback serves as a secondary transfer method when the Internet connectivity required for Aspera accelerated transfers (i.e., UDP port 33001, by default) is unavailable. When HTTP Fallback is enabled and UDP connectivity is lost or cannot be established, the transfer will continue over the HTTP protocol.

Note: This feature requires configuring your settings in IBM Aspera Enterprise Server. For details on how to perform these tasks, see the "Configuring HTTP and HTTPS Fallback" topic in your transfer product's Administrator Guide.

You may configure HTTP/HTTPS Fallback in the Aspera Enterprise Server GUI or modify aspera.conf. To edit your settings within the GUI, launch Enterprise Server and go to Configuration > Global (tab in left pane) > HTTP Fallback (tab in right pane).

After modifying aspera.conf, run the following command (from Enterprise Server's bin directory) to validate your updated configuration file:

$ /opt/aspera/bin/asuserdata -v
