get a list of online users in asp.net mvc

Question

I have a page in my application which always shows updated list of online users. Now, to keep the list-which is stored in application object- updated, i do the below steps

Answer 1

Here is the white elephant solution.

Instead of maintaining this list in application object, maintain this list in database. Then you can use database jobs to work on this list periodically. Establish SQL notification on this object so that everytime this list is purged you get refreshed data in your application.
