                }
                if (-f $request_filename/index.html){
                    rewrite (.*) $1/index.html break;
                }
                if (-f $request_filename/index.php){
                    rewrite (.*) $1/index.php;
                }
                if (!-f $request_filename){
                    rewrite (.*) /index.php;
                }
