I've read the whole NginX wiki and couldn't find a solution yet. So would you be so gentle to tell me how to do this.

I have two (2) domains on the same website. Let's say "www.first.com" and "www.second.com"
The frontend php shares the same files and the only difference is in the layout so I must differentiate the layout based on the hostname header sent by client.

My goal would be to redirect to the www domain if an invalid subdomain is typed.

example: error.first.com must redirect to www.first.com as well as wrong.second.com must redirect to www.second.com

My setup when I was using a single domain was easy:


if ($host !~* "www.first.com") {
rewrite ^(.*)$ http://www.first.com$1 permanent;
break;
}


but now my need is to do something like:


if ($host !~* "www.first.com|www.second.com") {
rewrite ^(.*)$ (what to put here???)$1 permanent;
break;
}


Thanks to anyone able to help me out with this issue...
