I am setting up a Web server on a Mac Mini.
Let's assume that the website is at: www.mydomain.com
I also wish the user to be able to access the website from: mydomain.com
Should I be using an additional domain, or perhaps a domain alias? (from the set up screen in server)
Assuming that www.mydomain.com and mydomain.com should actually be the same web site, an alias would be the appropriate approach.
Alternatively, I prefer to setup mydomain.com as a separate website that is configured to be a redirect to www.mydomain.com. By doing so, the website can be reached both ways, but references (from users or search engines) will consistently be made to www.mydomain.com.
