When resolving which url a like or share action or comments should be attributed to, Facebook uses a process to resolve the canonical url for url that's been loaded. When a URL is loaded, the crawler will look for:
  • A HTTP 301 or 302 Redirect
  • The use of rel=canonical as described in RFC 6596. (Facebook's crawler only supports content, not HTTP headers.)

By controlling the canonical URL you can move content from one URL to another and retain like & share counts and published Facebook comments -- as long as you allow Facebook to continue to resolve the new URL into the old one.
