Subject: MINOR: mux-h1: Improve H1 traces by adding info about http parsers
X-Git-Tag: v2.6-dev1~342
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6580f2868e8828a8ea1c9e4a6481c9e54abfdd25;p=thirdparty%2Fhaproxy.git

MINOR: mux-h1: Improve H1 traces by adding info about http parsers

Info about the request and the response parsers are now displayed in H1
traces for advanced and complete verbosity only. This should help debugging.

This patch may be backported as far as 2.4.
