Accessing Session from inside a HTTPHandler
Here something I didn’t know before. By default, you cannot access the session from within an Asp.Net HttpHandler. To be able to do that, your handler class has to implement an extra interface:
System.Web.SessionState.IRequiresSessionState
So, the declaration of your class looks like this:
If you don’t do this, and try to access Session object from within the Handler code, then you will get an Null Object Reference exception. It didn’t take long to find out that it was the session which was giving the null exception, however it wasn’t intuitive.
