This is important for our site, as no result of a web-form post should
be cached.

Before Windows XP Service Pack 2 a correct error Message "Warning:
Page expired..." was shown. The customers understood!

After installing SP2 the error Message "Page cannot be displayed" is
shown. It turned out that the IE Option "Show HTTP Friendly error
message" has to be turned off to get the old error message.

I have noticed that, but did not know it was the result of SP2. I don't
know what Microsoft thinks is "friendly" about a generic error page that
does not tell you what the problem is.
