Subject: Ignore leading whitespace when looking for requests and server replies,
X-Git-Tag: SQUID_3_0_PRE1~3404
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5ede6c8f55181af670fde110e9f262beea2e4ee3;p=thirdparty%2Fsquid.git

Ignore leading whitespace when looking for requests and server replies,
to make HTTP a bit more robust. Don't bail out if we receive a empty
line where a request-line is expected (a SHOULD in rfc2068).
