We are trying to monitor  http://www.netselmarina.com/ on OpManager. Site is up but when i hit test URL it returns " The URL http://www.netselmarina.com is down, Reason : Host Unavailable". I checked wireshark outputs, when i hit the Test URL, i get HTTP 303 first and then HTTP 200. I guess it is because of URL redirection?

So how can i monitor this URL now on OpManager?
