Well, no. Unless you have a web browser on you Spinneret, and the Spinneret connected directly to the Internet, not behind any firewall or NAT device, that page is of no use for this purpose.
Edit: Oh, stupid me. You can use this page to ensure relaying to your Spinneret server via your firewall is set up ok, so you can connect to it from the Internet. Need another coffee to wake up, methinks.
