HTTP Monitor with authentication (F5 LTM 11.6)

Hello,

 

I'm trying to implement a simple HTTP monitor using authentication on a Windows Server 2012 R2, but it doesn't work. Server receives HTTP request but it responses with 401 unauthorized user error, because it doesn't receive neither user nor password that I configured in HTTP monitor. I don't see any username in the server logs. In the monitor I've configured a simple HTTP request and configured User Name and Password in the corresponding sections.

 

Send String : GET /Application HTTP/1.0\r\n

 

F5 LTM versión : 11.6

 

Could anyone help me? Do you know how to configure this simple monitor?

 

Thank you very much. Regards.
