There needs to be two carriage return - line feeds at the end of a GET request. The monitoring daemon appends one for you.

 

 

If you use HTTP 1.1, you can tell the server that LTM isn't going to try to re-use the TCP connection:

 

 

GET / HTTP/1.1\r\nConnection: Close\r\nHost: \r\n

 

 

You can test this using netcat from the command line of the BIG-IP:

 

 

echo -e "GET / HTTP/1.1\r\nConnection: Close\r\nHost: \r\n\r\n" | nc 1.1.1.1 80

 

 

Replace 1.1.1.1 with the actual IP address of the server you want to test to.
