Discussion
Context.Session.SaveFileToSessionFile() saves the contents of the source file to the current session. The behavior of the function will vary depending on the server and whether session storage is enabled. When running Alpha Anywhere Application Server for IIS the default setting is to write the data into a collection that must be stored and retrieved on each request. Enabling session storage causes the server to store the data separately from the session state collection. This greatly improves performance when files are stored as part of the session state. Alpha Cloud always uses session storage. File objects are stored on Amazon S3 and managed by Alpha Cloud. Alpha Anywhere Application Server (classic edition) stores files on disk, but fully supports session storage as an option. Check Context.Session.CallResult.Success before using the return value.
