My last test results I stated were not correct, right after writing the note it started to fail all over the place. I placed in the code:

Response.Expires = -1
Response.AddHeader "Pragma","no-cache"
Response.AddHeader "Cache-control", "no-store"

at the top of each ASP page I had problems with and it now seems to work correctly. Is there a way to make it global to all ASP pages.
