welcome to WebmasterWorld, ultrafade!

when you request http://www.example.com/site what status code are you getting?
i assume it's a 404 with the "this link is broken error".
you should be responding with a 301 status code and this HTTP Response header:

Location: http://www.example.com/


as lucy24 mentioned, how you do that depends on your configuration.
