It is possible by doing a bit of rewriting and tweaking of URLs.
Here's the general idea:
RewriteCond %{HTTP_COOKIE} MYCOOKIE
RewriteRule ^(.*)$ /DONTCACHE$1
ProxyPass /DONTCACHE http://backend.foo.bar/
ProxyPassReverse /DONTCACHE http://backend.foo.bar/
CacheDisable /DONTCACHE
or something like that.

Subject: [EMAIL PROTECTED] mod_cache and conditional disabling
Hi,
As part of implementing a short term performance improvement, we're looking at
using a caching reverse proxy.
In essence we need to be able to disable mod_cache on a reverse proxy
configuration for certain classes of users only.
Users are able to be identified via Cookie and hence we can get an Env set for
that identification. But I can't figure out a way to disable the caching based
on this information.
Unfortunately, all the URL's remain the same for normal and "special"
users, so the normal CacheDisable Directive don't work.
I've tried using mod_rewrite and a proxy rule (ie [P]) without any success
- the resulting output is still cached, tho that could be PEBKAC.
Any ideas or insight would be greatly appreciated.
Cheers!
- Steve
