Jen,

 

I wonder if it's something to do with the HTTP version. F5 monitors use HTTP 0.9 by default. You can change this in the monitor string by adding the version manually e.g. GET / HTTP/1.0 or GET / HTTP/1.1. If using 1.1 then you are required to add host and connection headers e.g.

 

Host: www.yoursite.com Connection: close
