    GET /default.aspx HTTP/1.1\r\nHost: www.whatever.com\r\nConnection: Close\r\n\r\n

     

    If you use the HTTP iApp template, entitled 'f5.http', that's included with your BIG-IP system, it'll set up the monitor for you. You just need to provide the FQDN (www.whatever.com), and the requested resource (the default is "/", and in your case you'd change it to "/default.aspx").

usually works well for me.

    Some HTTP servers (like IIS) default to needing HTTP/1.1 connections, so this won't work for everything. Also the Host header isn't required for HTTP/1.0 connections.

    though host is not required for http/1.0, it is valid. I agree though, yours is a better string, I am just lazy and don't like to type Connection: Close. I didn't know that about IIS, they must configure all of ours to support 1.0 because I have never run into an issue. Thanks for the tip.
