Question

Im using outproc session that is managed by aspnet_state. Sometimes I get run time errors saying that the session is invalid. So I wanted to check if the session is valid for every request I make. But I couldn’t find a proper way to do it like in this Question using Java.

Here is the code I’m using right now in the page_preinit event.It looks ugly but it works.

            Try
                Dim x = Session.Keys().Item(0)
            Catch ex As Exception
                Session.Clear()
            End Try

Does any one knows a better approach?

Thanks

Answer 1

Actually I solved the problem by checking the first element of the session( session.item(0) )
I put the code in try catch . if the there is an exception I just clear the session. This code is in a basepage for all my pages.

so in the preinit event my code look like this

Private Sub Page_PreInit(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.PreInit
    Try
        Dim x = Session.Keys().Item(0)
    Catch ex As Exception
        Session.Clear()
    End Try
End Sub

It seems to be ugly but it does solve my problem.

Thanks everyone.
