Instructions

• Take this HTML file and host it on a web server you control.
• Obtain a free dynamic DNS hostname (for example at dyndns.org) and point it to your web server.

1. Use your web browser to access the html file (addressing it with the dynDNS hostname).
2. Use the dynDNS-provider's interface to set the host's address to the IP of the target server.
3. Quit your web server (or configure your firewall to reject connections).
4. Enter the address of the web page that you want to access (for example "index.html"), omitting the hostname (don't enter something like "intranet.local/index.html" or even "http://intranet/index.html", this script is quite dumb).
5. Press "start". If everything worked fine, a textarea containing the page's source code should appear in a couple of seconds.
