Hi

I currently have some code which creates a cache item when a user signs into the application.

I would like to know how would i be able to remove this cached item if the user closes the browser without signing out?

You cannot handle the close button event consistently across many browsers.
As a result, it may be best to set an expiry on cache data.
For e.g.when you logon, you could set the cache expire to 30.
Response.Cache.SetExpires(DateTime.UtcNow.AddMinutes(30));

Another approach could be to have a logout button and add the following code -

C#

Response.Cache.SetExpires(DateTime.UtcNow.AddMinutes(-1));
 Response.Cache.SetCacheability(HttpCacheability.NoCache);
 Response.Cache.SetNoStore();
