Is that considered a duplicate?

[popoman]

Well, Google has my www.domain.com indexed and the domain.com and also a subdomain.domain.com, the www.domain.com is the only one that was recently cached and the others are a bit outdated. Since I use mod rewrite redirect in my .htaccess they all go to my www.domain.com and that's what google shows when I do the site:domain.com function, all three have pretty much the same title and description as the www.domain.com, newer and older cached versions are the only difference, so would that count as a duplicate or is it ok and google understands the mod rewrite? btw, I erased my subdomain a couple of months ago and it's still indexed...

Thanks!

It was a problem sometime ago, I think now google knows that it is not duplicate with and without www.

Thanks, but what about my subdomain which doesn't exist but is cached on google with the same title and description as my www.domain.com. I think it happened coz the google spider simply went to my domain from my subdomain address coz of the .htaccess, but is that ok?
