Hi Guys,
Maybe a really stupid question. Please don't flame... But I am also
maintaining a web-site on top of the squid caches I maintain... With exactly
the same problem. The information regarding these headers is not so commonly
available... I'm probably looking for the wrong words...
Could you sum up what a web-designer could put in a
not-supposed-to-be-cached-page in the <HEAD> area, or if it's a hidden
cgi-bin script, what could be put in the first couple of lines ?
Thanks
Walter.

Thank you all for responding to this email. The bottom line is no there
is not a list of non cacheable sites. I just wish more web masters had to
deal with caches, they might just get a better understanding of what is
needed to make thing work better.
Thank you again...
