Subject: Update netdb when tunneling requests (#314)
X-Git-Tag: SQUID_4_5~12
X-Git-Url: http://git.ipfire.org/gitweb/gitweb.cgi?a=commitdiff_plain;h=052395d73216e8da08fcb872017081a9c7ad2cc6;p=thirdparty%2Fsquid.git

Update netdb when tunneling requests (#314)

Updating netdb on tunneled transactions (e.g., CONNECT requests) is
especially important for origin servers that are only reached via
tunnels. Without updates, requests for such sites may always through a
cache_peer, even if a direct connection to them is much faster.
