Thanks Rob.

This is probably OT for the thread but as long as we are covering
all these 'caching' issues let me ask you something.

Are you saying that when SQUID receives a response that has
"Expires: -1" in the response headers that it WILL, in fact,
CACHE it?

Doesn't "Expires: -1" always mean ALREADY EXPIRED
and "no need to cache it"?

I was under the impression that it had become General Practice
out there in Internet land that if you don't want inline Proxies to
cache anything the only 'generic' thing that seems to work for
all Proxies ( old, new and in-between ) is "Expires: -1".

Or have people just come to believe it stops 'caching' because
it just 'looks' that way ( since document is being re-validated
but it actually DID get written to SQUID's cache? )?

Thanks in advance...
