internal location keepalive_requests issue

[crasyangel]

location /hls {
            error_page 404 = @hls;
            keepalive_requests 1000;
        }

        location @hls {
            # Serve HLS fragments
            types {
                application/vnd.apple.mpegurl m3u8;
                video/mp2t ts;
            }
            root /tmp;
            add_header Cache-Control no-cache;
            keepalive_requests 1000;
        }

keepalive_requests must be large enough in this two location meanwhile
if set keepalive_requests to 0 or 1 in /hls or @hls, keepalive_requests
would not work in the other location
