Sessions not working while working with windows + web application

Question

Hi, I've a winform and i place a webbrowser control in that form. I'm giving default.aspx as webbrowswer url.

like this

Uri myuri = new Uri("http://192.168.1.1/test/default.aspx"); webBrowser1.Url = myuri;

now i'm storing some values in session (default.aspx page)

but those are now working for me. Every time it is showing null values in session.

What is the problem

thanks in advance Nagu
