Curious, it seems that Squid, when receiving a web page with the no-cache or
expires tags will not send it back to the client after it expires, but I was

If the site goes down and we have that cached copy in memory or on disk, why
not send it back instead of the "read timeout" message. This happens (a lot)
with It seems to get overloaded a lot, the link goes
down, etc.

This is how Netscape's internal cache works (if it can't contact the host,
it displays the previously cached copy even if the page instructed not to
cache or to expire).
