From 01e8e998fc6e5234fef11bcb3d27270fcfd04bce Mon Sep 17 00:00:00 2001 From: Justin Erenkrantz Date: Mon, 15 Apr 2002 02:58:11 +0000 Subject: [PATCH] Allow empty Host: header arguments. Previously, request that sent: GET / HTTP/1.1 Host: would get a 400. RFC 2616 specifically allows for a "blank" host field. The read_request code properly handled this, but the fix_hostname in vhost.c would cause the 400. Now, simply return in fix_hostname when we see a blank hostname rather than erroring out.
