Learn to Add or Remove the www Prefix in Domain URLs

This article explains how to change the www prefix in the URLs associated with your domain. For instance, users will immediately be routed to mydomain.com or vice versa if they input www.mydomain.com into their browsers.

It is recommended that, while thinking about Search Engine Optimization (SEO), a website react to either http://www.mydomain.com or http://mydomain.com, but not both. This is because material on www and non-www domains is viewed by the search engine as duplicate, which might lower the site’s rating.
