Decides whether a particular header may be cloned from the received Clients request to our outgoing fetch request.

RFC 2616 sect 13.5.1 - Hop-by-Hop headers which Squid should not pass on.

Proxy-Authorization:: Only pass on proxy authentication to peers for which authentication forwarding is explicitly enabled

RFC 2616 sect 13.5.1 - Hop-by-Hop headers which Squid does not pass on.

Connection:

TE:

Keep-Alive:

Proxy-Authenticate:

Trailer:

Transfer-Encoding:

Upgrade is hop-by-hop but forwardUpgrade() may send a filtered one

OTHER headers I haven't bothered to track down yet.

WWW-Authorization:: Pass on WWW authentication

Note: Assume that talking to a cache_peer originserver makes us a reverse proxy and only forward authentication if enabled (see also httpFixupAuthentication for special cases)

Host:: Normally Squid rewrites the Host: header. However, there is one case when we don't: If the URL went through our redirector and the admin configured 'redir_rewrites_host' to be off.

If-Modified-Since:: append unless we added our own, but only if cache_miss_revalidate is enabled, or the request is not cacheable, or the request contains authentication credentials.

Note: at most one client's If-Modified-Since header can pass through

If-None-Match:: append if the wildcard '*' special case value is present, or cache_miss_revalidate is disabled, or the request is not cacheable in this proxy, or the request contains authentication credentials.
