Hi Steve,

 

Thanks for your reply. I also was wondering if I had more in there than I needed. I have this monitor applied to a test pool of servers so the good thing is I'm able to alter it on the fly and see the results. I tried a couple of variations including: GET /branding/_1_1/logo_uchc.gif HTTP/1.1\r\n\r\n\ and GET /branding/_1_1/logo_uchc.gif HTTP/1.1\r\nConnection: Close\r\n\r\n but the monitor then fails in both cases. I'm thinking I might just need to leave it the way it is since I don't fully grasp the syntax.
