Redirect subdomain.domain.com to www.subdomain.domain.com

  • 772

We have currently a wildcard vhost accepting all domain request.

I want to redirect subdomain.domain.com to www.subdomain.domain.com so my wildcard will answer

One exception, I dont want to redirect www.domain.com to www.www.domain.com

How to achieve that ? I've put together (outside the wildcard block) but it's not dealing with the exception and not sure about the variable thing

if ($http_host ~ (.*).domain.com) {
    set $test P;
}

if ($http_host != www.domain.com) {
    set $test  "${test}C";
}

if ($http_host != www.*.domain.com) {
    set $test  "${test}D";
}

if ($test = PCD) {
    rewrite ^(.*)$ www.%1.domain.com$1 permanent;
}

Thanks

  1. I would use this:

    server {
    listen 80;
    server_name www.example.com example.com;

    # this is default server.
    ...
}

server {
    listen 80;
    server_name www.*;

    # here www.*.example.com
    ..
}

server {
    listen 80 default_server;
    return 301 http://www.$host$request_uri;
}
