vhost that binds to 'any host' -> no server_name

[gdhbashton]

Hi,

From looking at templates/vhost/vhost_header.erb, server_host will always be set in any vhost.

Is it possible to make this optional for the case where a client does not send any Host: header (e.g. a load-balancer check), hence nginx will use the vhost as a 'fallthrough'. This would also be useful for "301 redirect everything to www.canonicaldomain.com"

Cheers,
Gavin.

This can be accomplished by using '' as one of the attributes of 'server_name'. That is, you can use '' only as a fallback, or include '_' in server_name array for whichever vhost you want to be default.

This should probably be better documented, but it does work (and it's the convention nginx already uses / documents).
