Force WWW on multiple sites

[cmgmyr]

Hello everyone,

I have a site where any number of other domains can point to it. Right now I just have:

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

Which obviously just works for domain.com how can I adjust this so it forces the redirect for any domain that comes through?

 

Thanks in advance,

-Chris

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

Thanks, worked great!

Just as a word of warning, this will mess-up if you have any subdomains as it will also redirect http://subdomain.domain.com to http://www.subdomain.domain.com.

Oh, that's not so great. Is there a way to exclude some sub domains? I'm only using a few of them so it would be easy to manually update.

For a finite number of sub-domains you could use something like...

 

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

 

Or if all your domains are in the same TLD...

 

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

 

Depending on what domains you are working with will depend on what is the best solution.
