GTM 11.x HTTP health Monitor URL

Hi Guys, just a quick one to confirm so i do the right thing, i am creating http health monitor to check a URL then check the receive string, here below is what i setup on my GTM 11.X

 

Send string [ HEAD HTTP/1.1\r\nHost: \r\nConnection: Close\r\n\r\n]

 

Then

 

Receive String: HTTP/1.1 200 OK

 

let know if i am doing right as you also note that i am starting send string with HEAD not GET let know if this will work.

 

also is there a way of testing this before applying to server please?

 

Thank you in advance
