Best way to only allow specific file extensions?

[Cliff Wells]

Okay, so if I understand you, you want:

1) all requests for particular extensions and directories to be proxied
to a backend

2) everything else to return 444


location ~ (/?|\.html$|\.jpg|\.php|\.png|\.css|\.ico|\.js|\.swf|\.gif|robots\.txt)$ {
    proxy_pass  http://www.domain.org:80/;
}

location / { return 444; }


Is that closer to what you want?
