Redirect the non-www version of the site to the www

Question

In wordpress site how to Redirect the non-www version of the site to the www version to remove duplicate content

Answer 1

You need to setup it in your .htaccess file, it should looks like this one:

<IfModule mod_rewrite.c>
RewriteEngine On

RewriteBase /

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

RewriteRule ^index\.php$ - [L]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

Answer 2

This code is similar to Eugene’s, but it will redirect any domain that is not your main domain with “www” to the correct address. Handy if you have multiple top-level domains.

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /

# These are the lines that do the trick
RewriteCond %{HTTP_HOST} !^www\.yourdomain\.com$
RewriteRule .* http://www.yourdomain.com/$0 [L,R=301]
</IfModule>
