As of the latest release at this time (Beta 2), new installs of Graffiti CMS default to using just the domain name (http://jeftek.com) for your site. All requests to the domain as www.jeftek.com will be redirected to the jeftek.com site via a 301 redirect which is search engine friendly. There was a discussion on the GCMS forums as to whether it was a good/bad to have the www in the domain name which you can read here.
But what if you want to use www.jeftek.com because you feel it is the best possible address for your site? It’s a simple edit to the web.config file in your site:
<!–Helps ensure good SEO and stops duplicate content. Many search engines treat www. and no www. as two seperate links. –>
<add key="Graffiti::RequireWWW" value="false"/>
<add key="Graffiti::RequireWWW" value="true""/>
Now all requests to the short name will be re-directed to the www name for all of your links. Expect search engines to re-classify them as they are discovered as well. I originally used the short name for this site, but then decided it was best to still stick with the WWW version due to the current usage habits on the web.
Update: I decided I wanted to use http://jeftek.com as this sites main URL instead of with the WWW. This is going to cause me some search engine confusion for awhile, but I felt it was best to make this change now to minimize the effect later on.
