I'm currently using Apache 1.2.5 with proxy/caching features
enabled. Is there away to determine whether a request for a
document was served from the web server's cache?

I thought the status code of 304 indicated it had been retrieved
from cache, but apparently this code is also returned when the
request is satisfied by client side cache.

Any ideas,

Lukas

Yes, that's right. 304 isn't really related to the server-side of
proxy/cacheing. If you see a 304 in the access_log it means that the client
had the content in its cache, and it is not out-of-date. See the
HTTP/1.1 spec for more details.
