Well, the idea being that you don't want to cache pages that are session
specific, or post specific. You could end up with a _huge_ set of cache
files :)

I'm thinking more for, say, a large tree of html documents generated from
xml with xsl: you want to do the "render" once and then be able to serve it
out to 8million people, etc. This isn't intended for form pages, session
specific stuff, etc, as the files are stored in the filesystem, unencrypted.
(me = security freak :)

This cache has nothing to do with zend's caching - it only caches page
output - so if you have cached bc php, you'll see even _more_ of a
performance jump. Zend cache does the actual bytecode... Actually - andi, do
you have performance numbers for r2 on a zend cache-enabled box? I'd love to
see 'em :)

Also, note that you have to _explicitly_ request a page be cached, not the
reverse. (this will be the same for modules)

So there isn't really anything like "turn it off" because it isn't "on"
unless you specifically request it :)

Really?

Oh!, crap. I know what that is. I'll do a synch right now.. danke :)
