Web-forums (aka webboards) are inefficient analogs of newsgroups/mailing
lists. Competent people prefers newsgroups. But engineers of our
organization should use these forums, because they are not gated in
Usenet.

They are usualy made with PHP, each page is dynamic, so remote webserver
issues a no-cache pragma. But each page contains a lot of information
(top-level server menus, banners, some javascripts...). So, viewing even
small (<1kb) message forces loading of all this html stuff (up to 50kb in
cases of idiot webmaster, often up to 20kb).

I think that partial careful caching of this stuff can save us a
traffic.

I know. Really it's my idea. But chief looks in daily generated proxy
statistic, and see that most of traffic is from these sites. He is agree
that there is a reason to try some optimization.
