Is there a way to determine the number of users that have active sessions in an ASP.NET application? I have an admin/tools page in a particular application, and I would like to display info regarding all open sessions, such as the number of sessions, and perhaps the requesting machines' addresses, or other credential information for each user.
ASP.NET Performance Counters like State Server Sessions Active (The number of active user sessions) should help you out. Then you can just read and display the performance counters from your admin page..
