Subject: [PATCH] githttpbackend: use REMOTE_ADDR for deleted identifier
Date: Thu, 12 Sep 2019 23:16:52 +0000
Message-ID: <20190912231652.14816-1-e@80x24.org> (raw)

REMOTE_HOST is not set by us (it is the reverse DNS name) of
REMOTE_ADDR, and there's few better ways to kill HTTP server
performance than to use standard name resolution APIs like
getnameinfo(3).
