Apache – How to use htaccess to redirect non-www traffic to www?

What does this mean?

It means automatically redirecting http://domain-name.com to http://www.domain-name.com.

There are many benefits of redirecting traffic from non-www to www.

The main advantage is, it will avoid duplicate content in search engines like Google and Bing. It will also give a consistency to your website.

So how to implement this?

Just copy paste the below three lines in your .htaccess file.

{code}

RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]

{/code}

Now your non-www traffic is redirected to www traffic.
