Hello everyone! I recently switched my main webserver (where I host clients' websites) from apache to nginx and I wrote a custom generic configuration file to handle everything in one place, so domains and subdomains are handled on the fly by creating directories and subdirectories. Here's the relevant snippet:

server {

listen 80 default;

if ($host ~* ^(.*)\.(.*\..*)$) {
set $sub $1;
set $domain $2;
}

server_name _;
server_name_in_redirect off;
root /var/www/vhosts/$domain/$sub;
access_log /var/log/nginx/access.log combined;
error_log /var/log/nginx/error.log error;

include /etc/nginx/conf/wordpress_params;

location / {

root /var/www/vhosts/$domain/$sub;
index index.php index.html;

Everything works just fine as nginx is a great product ;-) Now, my only problem lays in the fact I haven't been able to write a regexp to setup a global redirect from, eg, domain.com to www.domain.com. Could anyone help me on this?

Thanks,
Alessio
