Does anyone know of a way to have a FileMaker solution check a web site to validate a key code?

I have a solution. I have key codes that my customers will get when they purchase. I don't have a good way to limit the use of that key code to keep one user from sharing it with anyone they like. I plan to maintain a black list of serial numbers so I can deactivate them with product updates, but until those updates happen, I don't have a great solution. Ideally I'd like the FileMaker solution to be able to reach out to a URL, and pull back a list of bad key codes and compare them to the key code in use. I don't want to be so strict about it that customers are overly annoyed when moving software around and such, but just a basic level of protection.

Thanks!

A plug-in that lets you post to a web server and receive the results would be the reliable way to implement that, e.g. Troi URL or ScriptMaster.

Or you could try it by setting a web viewer to your blacklist URL and then scraping the results. Make the web viewer tiny and the user won't even know it's there.
