I have over 1000 sites using my shopping scripts and I want to give best advice
to users with pricing information on their pages that may become out of date
while in cache.

I shall advise users with access to ASP or Perl of ways in which they can adapt
sensitive pages to send the more effective (than META tags) http header.

Any advice gratefully received......

Rodney
