Subject: MINOR: mux-h2: add a new dummy stream for the REFUSED_STREAM error code
X-Git-Tag: v2.0-dev1~324
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8d0d58bf6a11e7267ca05303b46254198d19b0e5;p=thirdparty%2Fhaproxy.git

MINOR: mux-h2: add a new dummy stream for the REFUSED_STREAM error code

This patch introduces a new dummy stream, h2_refused_stream, in CLOSED
status with the aforementioned error code. It will be usable to reject
unexpected extraneous streams.
