301 redirects asp.net VWD

Hello!

I want to do a couple things, and I'm sure they're remedial for many, but they're complicated for me.

First, I want to make sure that when someone types mydomain.com, they're redirected to www.mydomain.com -- so it always uses the www. I know that's better for search engines and duplicate content.

Secondly, I have some pages that I moved to another folder. So instead of getting a customerror when they go to www.mydomain.com/services/exactscan.aspx, they're automatically redirected to www.mydomain.com/products/exactscan.aspx.

I'm not sure whether it's more recommended to use .htaccess in my root, or to use my web.config in Visual Web Developer.

Any and all feedback would be sincerely appreciated!
