apache redirect from non www to www

Question

I have a website that doesn\'t seem to redirect from non-www to www.

My Apache configuration is as follows:

RewriteEngine On
### re-direct t         


        

Answer 1

I've just have a same problem. But solved with this

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

This rule redirecting non-www to www.

And this rule to redirecting www to non-www

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