My Nginx config is catching all subdomains without specifying a wildcard. I have created an special config for each subdomain, but seems that all subdomains pass trough the main domain configuration. I have discovered this by removing the subdomains configuration files from nginx.conf and watching how it still catches all the subdomains, so when I send a request to uk.domain.com, instead of Nginx catching the subdomain configuration, goes through the main domain configuration. This is causing trouble with applying mod_pagespeed individually to each of the sites and also managing the GA universal code.

The config for the main domain is this :

server ogv

HHVM config with fallback to fpm :

location ~ .(hh|php)$ 
 proxy_intercept_errors on;
 error_page 502 = @fpm;
 try_files $uri /index.php;


 fastcgi_keep_conn on;
 fastcgi_pass unix:/var/run/hhvm/hhvm.sock;
 fastcgi_index index.php;
 fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
 include fastcgi_params;


location @fpm 
 try_files $uri /index.php;
 include fastcgi_params;
# fastcgi_pass unix:/var/run/php5-fpm.sock;
 fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
 fastcgi_index index.php;
 include fastcgi_params;
# fastcgi_pass unix:/var/run/php5-fpm.sock;
 fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
 fastcgi_index index.php;
 fastcgi_pass 127.0.0.1:8000;
 fastcgi_buffers 32 16k;

Wordpress Multisite rewrites :

# Rewrite rules for WordPress Multi-site.
if (!-e $request_filename) 
rewrite /wp-admin$ $scheme://$host$uri/ permanent;
rewrite ^/[_0-9a-zA-Z-]+(/wp-.*) $1 last;
rewrite ^/[_0-9a-zA-Z-]+(/.*.php)$ $1 last;

1.) Remove your default config

rm -R /etc/nginx/sites-enabled/*

2.) Move your Configurations into the sites-available folder

mv /etc/nginx/*.comain.com /sites-available

mv /etc/nginx/anotherdomain /sites-available

3.) Link all Configurations in the sites-enabled folder to "enable" them.

ln -s /etc/nginx/sites-available/anyconfig /etc/nginx/sites-enabled/anyconfig

4.) Reload Nginx

service nginx configtest

service nginx reload

Check all your Configuration for the following Parts in the listen directive:
"default_site" and "_"

Both work as an Catch all mechanismus.

Edit nginx.conf

remove all includes and add:
include /etc/nginx/sites-enabled/*

Following this procedur, you have no "Wildcard" Nginx config anymore. To enable "Catch all", just create a new config, or edit a existing config and add "default_server", looks like:

server

listen 80;

listen 443 ssl default_server;
