ltm monitor http QA_ShortURL_Monitor {

 

defaults-from /Common/http

 

destination *:*

time-until-up 0

 

timeout 61

 

username DOMAIN\\svc_f5HTTPMonitor

 

}

 

 

I had to remove the trailing \r\n as it was causing malformed headers in the HTTP request which it appears is a known bug when using NTLM auth on a monitor.

 

 

Thanks
