Session state

I'm accessing two aspx from an applet using http requests.

On one of the aspx I insert a variable/value in Session.

On the other, I get the the value from the inserted variable.

This process is made in two stages, one at a time, so no sinchronization problems are in case.

The SessionID are in both cases the same.

What can be the problem?

I suspect that since the two calls are made from the browser (and no sumbit/redirect is made), the server creates two diferent sessions, one for each http request with the same SessionID. Any ideas, solutions on this? I've seen that the Session object has some properties related to synchronisation, but I found no functions that solve my problem.

Thx!
