Implement the IRequiresSessionState interface in your custom HTTP handler to identify that your handler requires read and write access to session-state values.

The following code example examines the current HTTP Handler property to determine whether it requires read and write access to session-state values.

Dim requiresSession As Boolean = False

If TypeOf (Context.Handler) Is IRequiresSessionState Then
  requiresSession = True
End If

bool requiresSession = false;

if (Context.Handler is IRequiresSessionState)
  requiresSession = true;
