tracking Domain alias

Hi everyone, great plugin!
Does anyone know how can I track a domain alias?
For example, my url is http://www.pugliò.it and I have a google analytics code to track it, but I ‘d like to track also my domain alias such as
http://www.puglio.it
http://www.puglio.com that redirect automatically to my main domain.

Thank you in advance
