How to I get the Facebook Authentication Plugin to work with example.com and www.example.com?

Question

When I registered the app with Facebook I had to specify site URL.  If I specify the URL in "example.com" format the authentication won't work if the user is on "www.example.com".  The reverse is true if I register the app the other way.  Does anyone have a solution for this?

Thanks!

Use a 301 redirect. For example, redirect all users from www.example.com to example.com. That way you only have one site and it should work.
