CirrostratusHi,
Don't get what is your issue? Is proposed Send string not working:
GET / HTTP/1.1\r\nHost: \r\nConnection: Close\r\n\r\n
I am using this kind all the time, maybe your backend server is not replying with 200 OK?
Just trace (tcpdump) traffic between BIG-IP self IP and backend host IP to see what's going on.
There is as well chance that your backend server expects proper IP or FQDN in Host header instead of just space - hard to say without knowing your environment.
