I'm using Windows Vista x64 with SP1, and developing an ASP.NET app with IIS7 as the web server. I've got a problem where my cookies aren't "sticking" to the session, so I had a google and found that there was a known issue with duplicate response headers overwriting instead of being added to the session. This problem was, however, supposed to have been fixed in Service Pack 1 for Vista.
Any ideas as to what my trouble might be?
Many thanks in advance.
