Subject: MINOR: mux-h1: Lower the case for Sec-Websocket-* headers when manually added
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8356c9c3945742a03a976c7431cf6a401b83b728;p=thirdparty%2Fhaproxy.git

MINOR: mux-h1: Lower the case for Sec-Websocket-* headers when manually added

During the message formatting, if websocket handshake key must be added by
the mux itself, the corresponding headers were not inserted in lowercase as
expected. It is not really an issue but it is not consistant with processing
on other headers. So let's fix it.
