HTTP monitor receive string : how to not take the '200 OK' into account

Hello,

I have to monitor a page which give in its body 'OK' if server is OK and KO if the server is down.

As a 'receive string', I use 'OK'. The problem is that 'OK' is already present in the 'HTTP/1.1 200 OK' (see below the output of the curl command)

I tried different receive strings, last attempt with this one: ^server But it does not work as F5 apparently considers the whole response as a single line.

Would you have an idea on how to make F5 to 'ignore' the "HTTP/1.[01] 200" ?
