Monitor when set HTTP server shows down but when I set it to TCP it works

Hi GLM, By default the http monitor send the string /\r\n to probe the server and expects standard code like 200 or 404 etc. If the server is not giving any of the codes something like Empty then the pool mark node down.

Use this command in bash curl -v http://10.1.1.1:80/\r\n and you will see * Empty reply from server. So verify the Webserver settings on the configured webservices.
