Hi

A couple of us in the IRC channel are keeping the wiki updated and we've come across some inconsistent behaviour with server_name.

The wiki currently states here: http://wiki.nginx.org/NginxHttpCoreModule#server_name
that server_name _; is treated specially for requests with no Host header, however, on the latest dev version this is not so.

If a request on the IP or on a domain without a matching server_block comes in then Nginx will either choose the server block with default_server flag in listen or the first one defined.

Question is, is this is a bug or should we update the wiki to no longer mention _?

Sincerely,
Martin Fjordvald
