Subject: It looks like int httpState->reply_hdr_state is always either 0 or 2.
X-Git-Tag: SQUID_3_0_PRE4~681
X-Git-Url: http://git.ipfire.org/gitweb/gitweb.cgi?a=commitdiff_plain;h=1a98175f1ed49051739a555da29d6a8a23a17b59;p=thirdparty%2Fsquid.git

It looks like int httpState->reply_hdr_state is always either 0 or 2.
I'm replacing it with the single-bit http_state_flags.headers_parsed.
