redirect/rewrite subdomain

[gomblue]

We had a development site here: "dev.example.com"

We now no longer use that address, as the site is now live here: "www.example.com"

Google is now indexing "dev.example.com".

Can I change my htaccess file to redirect all traffic to "www.example.com"? Probably a 301 in order to teach the search engines to only use "www.example.com".

I'd like all variations of "dev.example.com/example.html" traffic to be pointed to the homepage at "www.example.com".

Re: redirect/rewrite subdomain

After speaking with our host (Hostasaurus), we are going to delete the dev site. We really don't need a copy of the old site, now.

Indexing possibly the result of my using google toolbar.
