mod_rewrite - add www

Question

I\'m trying to force www for my site address with .htaccess:

RewriteCond %{HTTP_HOST} ^mysite\\.com$ [NC]
RewriteRule ^(.*)$ http:/         


        

Answer 1

The problem is right here:

RewriteCond %{HTTP_HOST} ^mysite\.com$ [NC]

^ specifies the beginning of the string while $ specifies the end.

In order to make it work you need to have a wildcard select after the .com or .+.

to reiterate what Alex said:

 <IfModule mod_rewrite.c>
   RewriteCond %{HTTPS} !=on
   RewriteCond %{HTTP_HOST} !^www\..+$ [NC]
   RewriteRule ^ http://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
 </IfModule>

Answer 2

From the superb HTML5 Boilerplate .htaccess:

<IfModule mod_rewrite.c>
  RewriteCond %{HTTPS} !=on
  RewriteCond %{HTTP_HOST} !^www\..+$ [NC]
  RewriteRule ^ http://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
</IfModule>

Answer 3

Actually, I have to disagree with Mr. Szanto.

It would appear the problem was not with the:

RewriteCond %{HTTP_HOST} ^mysite\.com$ [NC]

Through some additional research (via Google) I found that this worked great for me:

<IfModule mod_rewrite.c>
  RewriteCond %{HTTPS} !=on
  RewriteCond %{HTTP_HOST} ^mysite\.com$ [NC]
  RewriteRule ^ http://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
</IfModule>

Mr. Szanto's answer, while well formatted, seems to redirect all requests missing the 'www' to be redirected with the 'www' attached. This was not a desirable outcome with most subdomains. The above code only redirects if there is no 'www' AND no subdomain before the TL domain name.

Hope this helps others.
