Disabled duplicate "Host" headers (ticket #1724). Duplicate "Host" headers were allowed in nginx 0.7.0 (revision b9de93d804ea) as a workaround for some broken Motorola phones which used to generate requests with two "Host" headers[1]. It is believed that this workaround is no longer relevant. [1] http://mailman.nginx.org/pipermail/nginx-ru/2008-May/017845.html
