I am currently working on a blog and the site is structued such that when you go to the url eg: www.example.com
you are redirected to
www.example.com/blog/10-10-2010/new-product-released.html (the url you are redirected to changes to the most recent blog entry).
I was using a sitemap generator and the url www.example.com is displayed as 302 temporarily moved and I wanted to know what the effect was of this in terms of seo, also what would be the best way to cget this working for effective seo?
Secondly, in terms of the sitemap should urls in a checkout area for an ecommerce app be included?
Ps. I am using Apache on CentOS.
