The http_session_timeout public database option provides variable session timeout control. The option setting is in units of minutes. By default the public setting is 30 minutes. The minimum value is 1 minute and the maximum value is 525600 minutes (365 days). Web applications can change the timeout criteria from within any request that owns the session. A new timeout criteria may impact subsequent requests queued should the session timeout. It is up to the web application to provide the logic to detect if a client is attempting to access a non-existent session. It can do this by examining the SessionCreateTime connection property to determine if it is a valid timestamp. The SessionCreateTime value will be an empty string if the HTTP request is not associated with an existing session.
