[Zope] Caching How-To (was Cache concerns (was zope/proxy_pass configuration problem) configuration problem)

During the last couple of days I could finally figure out how to set 
up caching with mod_proxy. This morning I put together a caching 
howto and submitted it for review.

If it's accepted it will be available under 
http://www.zope.org/Members/rbeer/caching

I'm going on holiday now (Crete: wonderful greek island) and I'm 
going without my laptop so I won't answer any emails for the next two 
weeks ;)

>>SiteRoot in the main folder and create a separate folder called, say,
>>'http', which holds the http SiteRoot.  This solution will kill two birds
