Livesite Production Environment

Hi,

1.) What are the attributes of default.site mean?
2.) Can I have resources(images,files) and the site in the same directory structure, If yes then how?
3.) I have default.site in web/sites/UK/
I have pages in web/sites/UK/en/
and I have resources in web/UK/

Can anyone suggest how to control the resources accessed by the poges?

All reply will be highly appreciated

Thanks and Regards
Sui
