How to use regular expressions in server_name directive is 
documented here:

http://nginx.org/r/server_name

Note that regular expressions must be preceeded with "~" to 
distinguish them from normal names.

Syntax of regular expressions per se is documented in the PCRE 
library manual pages, see "man pcresyntax" for quick syntax 
reference.
