Hi

I need some guidance about SEO

We have a main site (CountryWebsite.com)
Also have mini sites for cities
like
City1Website.com
City2Website.com

etc

As the name says we are having city specific data on each city site and Country Data on main site

Now, my confusion is that can we use url rewriting for displaying City1.CountrySite.com OR www.CountrySite.com/City1/index.htm as City1Website.com

Will this be accepted by goolge and other search engines
