Yep i tried Mozilla and Opera and have no problems at all.
I have problems with the cache busting code in that article (slightly beyond
the scope of this issue i have).
IIRC its the code that was in aspfaq which has now been replaced by this
http://www.aspfaq.com/show.asp?id=2022
Response.ExpiresAbsolute = #2000-01-01#
Response.AddHeader "pragma", "no-cache"
Response.AddHeader "cache-control", "private, no-cache, must-revalidate"
so presumably there was something wrong with the previous code. In fact i'm
not entirely convinced about that to be honest!
