I just checked that site it uses:
Server: Mathopd/1.1b1

Don't forget that Jigsa wproxy is fullly http/1.1 compliant. I tried
to be as smart as possible with broken servers, but this one is out of
reach.

There is not much control available right now, more will be provided
when the caching algorithms become smarte (consider the current algo
as being level 0 of what could/should be done, ie its compliant and
useable).

Itis up to webadmins to setup their site properly. A proxy cannot hard
code rules such as "my.yahoo.com" pages should always be
refreshed. There are a number of doing so. Jigsaw default
configuration, for example, states that all HTML pages are cacheable
for two days, you can change this globally (at the extension level),
or on a per document basis (check the max-age attribute of the
HTTPResource)

Symantec runs it fine (and speed it up), that's the only com,piler
that I have checked. kaffe is the next one to test on my list.
