My asp.net application works fine when launched from its own browser, but when its launched from another web application (sharepoint webpart) using window.open it works until the user clicks and posts back, then the session is lost.
I think its related to cookies, because when I set the session state to be cookieless everything works fine.
Why does the sesssionid get lost in the NEW application when launching the app using window.open? I would like each application to have its own session cookie, I've tried setting the name of the cookie but the same thing happens, on the first post back the sessionid is lost??
Please help?
