HTTP Monitor Shows UP even Recv String is different

Hello Folks, Straight to my question, I have a monitor as below:

 

Send String: GET /app/ping HTTP/1.1\r\nHost:company.example.com\r\nConnection: Close\r\n

 

Receive String : active

 

I want my member to be down if I get back receive string other than "active".

 

Currently member is showing up even if the receive string is different.

 

How should i implement for this to work?

 

Any help is greatly appreciated! Thanks in advance!
