Count like Facebook on a different server.

Hey guys,

I have a problem with Facebook like count (using standard like, not application).
The problem is that the Web site is running on 2 different servers http://www.site.com/ , www2. site.com.

What is the application to carry him as count?

Was this work if the www and www2 is not included when passing the url?

Thank you
THA Lao
