From 76e0cd12f68f0b8173bc71ee6e9ad3ca453d5a28 Mon Sep 17 00:00:00 2001 From: "Dr. Stephen Henson" Date: Sun, 18 Oct 2015 00:16:23 +0100 Subject: [PATCH 1/1] Move auto Host adding to query_responder Check for Host header in query_responder instead of process_responder. This also fixes a memory leak in the old code if the headers was NULL.
