SYMPTOMS
When you view the Current Sessions dialog box for the Web Proxy service, sessions for users may still be present in the list for more than 15 minutes after a user has stopped using the proxy server or disconnected from the network.



CAUSE
This is normal behavior. The sessions time out after about 15 minutes of inactivity. Because of the connectionless nature of the HTTP protocol, the proxy server estimates how many sessions still exist.

For example, a user browsing the Web may be idle for several minutes. If the proxy server does not receive any further requests from the user after 15 minutes, the user is removed from the list. Otherwise, users remain in the list even if they have closed their Web browser or shut down their client computer.
