AFAICT having negative_ttl > 0 is a violation of HTTP/1.1 section 13.4 (last two paragraphs). If this is the case, I should set negative_ttl=0 when Squid is used as a general-purpose proxy server. I know that Squid doesn't claim full HTTP/1.1 support, but many clients nowadays use HTTP/1.1 would benefit from having Squid being to support so much of HTTP/1.1 as possible. Do you agree with this? http://www.w3.org/Protocols/rfc2616/rfc2616-sec13.html#sec13.4 Thanks, Christian
