Session Management
When an application session is established by using the /Quota/Logon URL, the following information is cached:
the date/time when the session was last accessed
the date/time when the LastUpdated field in the application session table was updated
a logged‑on DPM agent object
the permissions for the logged‑on user
an application log (AppLog) object.
The application session times out after 10 minutes of not being used. To change this interval, use the SessionTimeout web.config property. The application session is immediately removed if a request to the /UserAuth/KeepAlive URL indicates that the user session is no longer valid. If you try to use an application ID after the /Quota/Logoff URL has been used, an error is generated, indicating that the application session is unknown.
