No you do not have to pass values through the query string.

A cookie is issued to the user's browser on the first request (unless you are using cookieless session). This cookie is stored and can be accessed by any instance of that browser (including pop ups), until the cookie is cleared from the browser.

This means that the popup window should be able to access Session data for that user.

Does the client's browser have Cookies Enabled?
