[Zope] conditionally caching zope

[Navindra Umanee]

Hi, 

Currently our Zope setup (http://dot.kde.org/) can't gracefully take
the full brunt of our site hits, so we are using an Apache proxy/cache
solution which works very nicely.

For many pages however, I would like Apache to send cached copies IF a
certain cookie is NOT set, and otherwise, query Zope for a dynamic
page.  This tactic would enable us to handle Slashdotting while not
losing the settings of our regular readers.

Has anyone done this before?  Any suggestions?

Thanks,
Navin.
