Extended Content Verification (ECV) Content Check HTTP Health Monitor Receive String (2)

Yes, I ran a tcpdump on the BIG-IP while also running a curl on the BIG-IP. Correct, I do not get a "400 Bad Request" when using curl or the browser. Here is my Send String again: "GET /Login.htm?ReturnUrl=%2fpages%2ffscremote.htm&AspxAutoDetectCookieSupport=1 HTTP/1.1\r\nHost: SERVER\r\nConnection: Close\r\n\r\n", replacing "SERVER" with blank, BIG-IP, the NetBIOS name of the server, the FQDN of the server, and the DNS alias for the service running on this server.
