Robert...
I don't mean to harp on this issue but it IS partially relevant
since we are just trying to really understand the REALITIES
of caching here and not the 'urban legends'.
I have another (quick) question for you regarding this "Expires: -1"
thing.
If SQUID does, in fact, actually CACHE a response that is
showing up with "Expires: -1" in the response headers
( which means it cannot possibly EVER be 'fresh' )...
...then when in the heck does such a response ever
get REMOVED from the cache ( erased from disk ) ?
If it was already STALE when it arrived... then how can
it ever get MORE STALE and when would SQUID
purge this puppy from the disk?
Are all of these "Expires: -1" documents hanging around
forever in SQUID caches?
Yours...

I did - the paragraph I acked is 100% correct. Squid will cache and<BR>
revalidate before serving responses with Expires: -1.<BR>
