butting in with questions :)
with 2.3.x, RAM Cache Manager has no refresh/expire/max_age feature.  you get 
that with 2.4.x and above only.  so that might give users stale pages.  i 
know, i've encountered it.

i *really* think that there should be a RAM Cache Manager howto/best 
approach.  i'd like to write it, but i need inormation.  i'm currently 
caching my pages, but i'm not sure i'm doing it right.  properties such as 
REQUEST variables (there's two forms available. 1- at the method's page, 2-at 
the cachemanager page), statistics (seems that the url does have some effect 
on the cache hit rates), etc.  confirmation from product author/zc would 
really help.  i guess that i should really look at the source ..., and i 
will.  today.

now, for putting squid in front of zope.  how do others do this, when you 
have more than one server (using zeo).  there's the virtual parameter in 
squid, but i don't get it.  any body done this?

my solution for now is putting in caching manager, and if *really* necessary 
adding in another zeo client.

thanks
