Subject: [PATCH v4 08/11] http: tell server that the client understands v1
Date: Mon, 16 Oct 2017 10:55:29 -0700 [thread overview]
Message-ID: <20171016175532.73459-9-bmwill@google.com> (raw)
In-Reply-To: <20171016175532.73459-1-bmwill@google.com>
Tell a server that protocol v1 can be used by sending the http header
'Git-Protocol' with 'version=1' indicating this.
Also teach the apache http server to pass through the 'Git-Protocol'
header as an environment variable 'GIT_PROTOCOL'.
