Correct the 75% of all hits are on a script that can take anywhere from
a few seconds to a half an hour to complete. The script essentially
auto-flushes to the browser so they get new information as it arrives
creating the illusion of on demand generation.

A squid proxy would probably cause severe problems when dealing with a
script that does not complete output for a variable rate of time.

As for images, CSS, javascript and such the site makes use of it, but in
the grand scheme of things the amount of traffic they tie up is
literally inconsequential. Though I will probably move all of that
onto another server just to allow the main server the capabilities of
dealing with almost exclusively dynamic content.
