Facebook Like button: is it possible to change the URL of a page you share?

Can I change the URL of a page shared through the facebook like button? Is there any met开发者_开发知识库a tags for this?

When you are generating code for your like button it allows you to provide a url to like. If you want more customization options there is a whole set of OpenGraph meta tags that let you set url, image, description for your liked page and more.
