    Try adding a Host: header to your send string. I believe HTTP/1.1 requires it even if it is empty.

    Something like

    Thanks Dylan you were exactly right, I didn't realise Host: was a required parameter for http 1.1 (rtfm?). I added it with a blank address and it was fine. Thanks heaps for your help.
