Redirect site from www to non-www

It is better to make web site available with one URL. Many sites work with both wwww and non-www (naked domain) urls.

Using www or non-www is personal choice. One advantage of using wwww for URL is when you have lot of sub domains. If you use non-www url, cookies set by the domain will be available to sub domains. This will increase bandwidth usage as cookie need to be sent with every request browser make to web server.

Apache

If you are using Apache web server, you can redirect wwww to non-www url by adding following code in .htaccess file

Nginx

If you want to use same server entry for www and non-www, add following code to nginx server entry for the web site.
