This is similar to many of the other suggestions with a couple enhancements    No need to hardcode the domain  works with vhosts that accept multiple domains or between environments  Preserves the scheme  http https  and ignores the effects of previous   REQUEST URI  rules  The path portion not affected by previous RewriteRules like   REQUEST URI  is   RewriteCond   HTTP HOST    www    NC  RewriteRule          REQUEST SCHEME    www   HTTP HOST   1  R 301 L

I had a similar task on a WP Multisite  where the redirection rule had to be generic  for any given domain I d add to the network   I solved first adding a wildcard to the domain  parked domain   Note the   after  com   CNAME   domain com    And then I added the following lines to the  htaccess file at the root of my multisite  I guess it d work for any site   RewriteEngine On RewriteBase   RewriteCond   HTTP HOST   www         NC  RewriteRule        http    1  1  R 301 L    Hopefully this will help   ps  If you d like to redirect from not www to www  change the last line into  RewriteRule        http   www  1  1  R 301 L

lt VirtualHost   80 gt         DocumentRoot  what ever root to source         ServerName www example com          lt Directory  what ever root to source  gt           Options FollowSymLinks MultiViews Includes ExecCGI          AllowOverride All          Order allow deny          allow from all           lt What Ever Rules You Need  gt         lt  Directory gt        lt  VirtualHost gt        lt VirtualHost   80 gt        ServerName example com       ServerAlias   example com       Redirect permanent   http   www example com       lt  VirtualHost gt    This is what happens with the code above  The first virtual host block checks if the request is www example com and runs your website in that directory   Failing which  it comes to the second virtual host section  Here anything other than www example com is redirected to www example com   The order here matters  If you add the second virtualhost directive first  it will cause a redirect loop   This solution will redirect any request to your domain  to www yourdomain com   Cheers

Using the rewrite engine is a pretty heavyweight way to solve this problem  Here is a simpler solution    lt VirtualHost   80 gt      ServerName example com     Redirect permanent   http   www example com   lt  VirtualHost gt    lt VirtualHost   80 gt      ServerName www example com       real server configuration  lt  VirtualHost gt    And then you ll have another  lt VirtualHost gt  section with ServerName www example com for your real server configuration  Apache automatically preserves anything after the   when using the Redirect directive  which is a common misconception about why this method won t work  when in fact it does

If using the above solution of two  lt VirtualHost   80 gt  blocks with different ServerNames      lt VirtualHost   80 gt      ServerName example com     Redirect permanent   http   www example com   lt  VirtualHost gt   lt VirtualHost   80 gt      ServerName www example com  lt  VirtualHost gt        then you must set NameVirtualHost On as well   If you don t do this  Apache doesn t allow itself to use the different ServerNames to distinguish the blocks  so you get this error message    warn   default  VirtualHost overlap on port 80  the first has precedence      and either no redirection happens  or you have an infinite redirection loop  depending on which block you put first

Redirect domain tld to www   The following lines can be added either in Apache directives or in  htaccess file   RewriteEngine on     RewriteCond   HTTP HOST    RewriteCond   HTTP HOST    www    NC  RewriteRule   http  ENV protossl    www   HTTP HOST   REQUEST URI   L R 301     Other sudomains are still working  No need to adjust the lines  just copy paste them at the right place    Don t forget to apply the apache changes if you modify the vhost    based on the default Drupal7  htaccess but should work in many cases

-If you host multiple domain names  Optional  -If all those domain names are using https  as they should  -if you want all those domain names to use www dot domainName This will avoid doble redirection  http   non www to http   www and then to https   www   lt VirtualHost   80 gt  RewriteEngine On RewriteCond   HTTP HOST      www           NC  RewriteRule        https   www  1 1  R 301 L   lt  VirtualHost gt   And  lt VirtualHost   443 gt  RewriteEngine On RewriteCond   HTTP HOST    www    NC  RewriteRule        https   www   HTTP HOST  1  R 301 L   lt  VirtualHost gt   You should change the redirection code 301 to the most convenient one

This works for me   RewriteCond   HTTP HOST      www domain com      NC  RewriteRule         http   www domain com 1   R 301 L    I use the look-ahead pattern    www domain com  to exclude the www subdomain when redirecting all domains to the www subdomain in order to avoid an infinite redirect loop in Apache

I ran this      RewriteEngine on  RewriteCond   HTTP HOST    www     NC   RewriteRule     www        http   www   HTTP HOST   1  R 301 L    I need this to be universal for 25  domains on our new server  so this directive is in my virtual conf file in a  lt Directory  tag   dir is parent to all docroots   I had to do a bit of a hack on the rewrite rule though  as the full docroot was being carried through on the pattern match  despite what http   httpd apache org docs 2 2 mod mod rewrite html says about it only being stuff after the host and port

I found it easier  and more usefull  to use ServerAlias when using multiple vhosts    lt VirtualHost x x x x 80 gt      ServerName www example com     ServerAlias example com           lt  VirtualHost gt    This also works with https vhosts

RewriteCond   HTTP HOST    example com   NC  RewriteRule        http   www example com  1  R 301 L    This starts with the HTTP HOST variable  which contains just the domain name portion of the incoming URL  example com   Assuming the domain name does not contain a www  and matches your domain name exactly  then the RewriteRule comes into play  The pattern        will match everything in the REQUEST URI  which is the resource requested in the HTTP request  foo blah index html    It stores this in a back reference  which is then used to rewrite the URL with the new domain name  one that starts with www     NC  indicates case-insensitive pattern matching   R 301  indicates an external redirect using code 301  resource moved permanently   and  L  stops all further rewriting  and redirects immediately

Do not always use Redirect permanent  or why it may cause issues in future  If there is a chance that you will add subdomains later  do not use redirect permanent  Because if a client has used a subdomain that wasn t registred as VirtualHost he may also never reach this subdomain even when it is registred later  redirect permanent sends an HTTP 301 Moved Permanently to the client  browser  and a lot of them cache this response for ever  until cache is cleared  manually    So using that subdomain will always autoredirect to www     without requesting the server again  see How long do browsers cache HTTP 301s  So just use Redirect  lt VirtualHost   80 gt    ServerName example com    Redirect   http   www example com   lt  VirtualHost gt   Apache org - When not to use mod rewrite Apache org - Canonical Hostnames

To 301 redirect all requests made directly to the domain to www you can use  RewriteEngine On  RewriteCond   HTTP HOST                   2     NC  RewriteRule        http   www   HTTP HOST   REQUEST URI   R 301 L   The benefit of this is that this will work if you have any valid subdomains  e g  example com REDIRECTED TO www example com foo example com NO REDIRECT bar example com NO REDIRECT
