How to find how many people are online in a website
<p>I have to show how many people are online in that site. The site has developed by using ASP.NET 2.0. Currently I am using the Session start (increase by 1) and Session End Event (decrease by 1) in Global.asax.  But the Session_End Event not calling properly most of the times. Is there any better way to achieve this?</p>
