Monitors Won't Check HTTP Status Code

I'd also guess it's the \r\n's on the end of the send string causing the app to send a 400 response back to the client. You could confirm this by checking the web server logs or running a tcpdump on LTM filtering for the static self IP and pool member IP.

 

 

You can use a receive string like this to check for an HTTP 1.0 or HTTP 1.1 200 OK response:

 

 

HTTP/1\.(0|1) 200 OK

 

 

Or more simply, '200 OK' will usually do fine. 200 on its own will match the year in the Date header (or the Last-Modified header.
