Dim instance As IReadOnlySessionState

Implement the IReadOnlySessionState interface in your custom handler to identify that your handler requires only read access to session-state values.

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

Dim readOnlySession As Boolean = False 

If TypeOf (Context.Handler) Is IReadOnlySessionState Then
  readOnlySession = True 
End If
