index or try_files in reverse proxy

[meto]

Somehow i managed to make this work:

location / {
                index index.html index.htm index.php;

                try_files $uri $uri/ @proxy_backend;
                }


But i think that it should work with:

location / {
                try_files $uri $uri/index.php @proxy_backend;
                }
