With the debug enabled, I changed the receive string to HTTP 200 and observed the log, it doesn't make a gret deal of sense to me but I think this would be the relevant part:
10:15:18.679176: (_main_loop): wfd selected for addr=::ffff:10.20.15.32:8080 pending=1
10:15:18.679198: (_send_active_service_ping): addr=::ffff:10.20.15.32:8080
10:15:18.679230: send_active_service_ping: addr=::ffff:10.20.15.32:8080 writing GET / HTTP/1.1
Host:
Connection: Close
...
Can I just clarify what is currently happening? Am I understanding correctly that currently the only thing coming back is part of the http header containing the text "HTTP" before the connection is closed by the app server?
