Session variables that are defined in an Active Server Pages (ASP) page are empty when you attempt to access the values from other ASP pages within the frameset.
Internet Explorer 4.x and 5 cannot host the different frames of a frameset in the same process. Because ASP sessions are dependent on a Cookie that resides in the memory of the hosted process, different processes result in different Session Cookies and, therefore, different Sessions.
If your application must support Internet Explorer 4.x or Internet Explorer 5, then you should replace Session variables with Cookies. Ensure that the Cookies have an expiration date. This will result in the Cookie being written to disk. Regardless of which process the frame is hosted in, all frames will gather the Cookie information from the same location on disk.
