Subdomain Proxy/Rewrite with Nginx Proxy

Question

I want to take m.example.com and direct those requests to example.com/mobile/ with nginx. (The same nginx sever will be serving example.com)

Can someone help me with the config I would need? I can post my nginx.conf if needed, but I assume its something like:

location / { rewrite /([^/] +) /mobile/$1 break; proxy_pass http://127.0.0.1; }

Am I in the right ballpark?

You should use a server block for this to allow Nginx to use it's hash table lookup.

server {
    server_name m.example.com;

    location / {
        rewrite ^ http://example.com/mobile$request_uri permanent;
    }

    location /mobile {
        rewrite ^ http://example.com$request_uri permanent;
    }
}
