If you want to redirect all non-www requests to your site to the www version  all you need to do is add the following code to your  htaccess file   RewriteEngine On RewriteCond   HTTP HOST    www   RewriteRule        http   www   HTTP HOST   1  R 301 L

The following should prefix  www  to any request that doesn t have one  and redirect the edited request to the new URI   RewriteCond    HTTP HOST      www             NC  RewriteCond    HTTP HOST          RewriteRule                 http   www  1 1   R 301 L

I would use this rule   RewriteEngine On RewriteCond   HTTP HOST       RewriteCond   HTTP HOST    www    NC  RewriteCond   HTTPS s  on s   RewriteRule   http 1   www   HTTP HOST   REQUEST URI   R 301 L    The first condition checks whether the Host value is not empty  in case of HTTP 1 0   the second checks whether the the Host value does not begin with www   the third checks for HTTPS    HTTPS  is either on or off  so   HTTPS s is either ons or offs and in case of ons the s is matched   The substitution part of RewriteRule then just merges the information parts to a full URL

This is an older question  and there are many different ways to do this  The most complete answer  IMHO  is found here  https   gist github com vielhuber f2c6bdd1ed9024023fe4    Pasting and formatting the code here didn t work for me

This will do it   RewriteEngine On RewriteCond   HTTP HOST    www   RewriteRule        http   www   HTTP HOST   1  R 301 L

This won t work with subdomains   domain com correctly gets redirected to www domain com   but  images domain com gets redirected to www images domain com   Instead of checking if the subdomain is  not www   check if there are two dots   RewriteCond   HTTP HOST          NC  RewriteCond   HTTP HOST                  NC  RewriteCond   HTTPS s  on s   RewriteRule   HTTP 1   www   HTTP HOST   REQUEST URI   R 301 L
