After upgrading from asp.net 2.0 to 3.5, session do not work

[aspfun]

I just upgraded one asp.net 2.0 (using vs2008) app to asp.net 3.5 (using vs2010) but session do not work. (pass a value from one page to another page)

I used code in web.config file as below. Please help me.

<sessionState mode="InProc" stateConnectionString="tcpip=127.0.0.1:42424" sqlConnectionString="data source=127.0.0.1;user id=sa;password=" cookieless="false" timeout="120"/>

inproc and sql?
What you try here is storing the session in memory but using an sql server to store it and all these remotely.
Do you have a specific requirement for the session or it's just the default session?If so then remove all the session lines you have here from web.config.
If you need something specific then have a look here:
