So you're building squid's 'httpd accellerator mode' into apache, basically,
but taking advantage of the fact that the two parts are closely coupled to
increase speed further?
I've been thinking about doing this (with squid), to front-end an
apache/mod-perl that would mostly be used for less than 100% dynamic (and
therefore cacheable) content.
Being able to do it all in apache would be nice.
