VB.net session variable counter not adding on

Question

I have a master page with the following vb code in the code file...

Public Sub Page_Load(ByVal Sender As Object, ByVal E As EventArgs)

    If Not IsPostBack Then
        If Session("key") Is Nothing Then
            Session("key") = 0
        Else
            Session("key") = Session("key") + 1
        End If  
        Response.write(Session("key"))
        LoadData()
    End If

End Sub

This should write a number to the top of each page saying how many pages have been visited... It stays at zero all the time though.

Any ideas??

Answer 1

Be sure to search your code in your master page and containing page for any Session.Abandon()

I ran into this problem a while back and didn't realise another developer had put that in.

Answer 2

I've tested this and it works fine on my machine.

Ensure that your session timeout is set, otherwise it will expire resulting in Session("key") being set to 0 every Page_Load

Try adding the following to your web.config:

<configuration>
<system.web>
<sessionState timeout="120" />
</system.web>
</configuration>
