domain and it's alias

Hi,

inside my old domaine i have same applications like

1. www.Domain.com/aplication1/
2. www.Domain.com/application2/
3. .....

i created an alias which hits the same location

Like www.aliasDomain.com/application1   

After some months i want to know which domain is used more often domain.com or aliasdomain.com.

Note I use ODBC Logging in SQL but there is no domain field to look at. How could i get this information?

Thanks.
