Passing values from one asp.net applicatin to another

Hi....
I have searched for this topic in many places...but havnt got an exact solution.

Here is what I am trying to do in my project...

I have a page in which user after logging in, selects one out of the three radio buttons. User can navigate to one of the three different pages ( different application) depending on this selection. Some values have to be passed to target page depending upon user selection.

Now

1) I dont want to send it through URL.

2) No database .


Can it be done through Postbackurl.








Please help me.
