Re: Why Nginx redirect www to non-www urls?

I enabled the debug mode and in the log file I found out this line:
"^(GET|HEAD)$" matches "GET", client: xxx.xxx.xxx.xxx, server: www.mattiamerlini.it, request: "GET / HTTP/1.1", host: "mattiamerlini.it", referrer: "http://mattiamerlini.it/"

I think the referrer is the problem.

Is the problem clearer for you now?

Thanks
