Apache mod_rewrite: force www only if not in localhost

Question

I have the following in my htaccess to force the www in URLs: ``` RewriteCond %{HTTP_HOST} !^www\. RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L] ``` How do I only apply this if not on localhost? Is there some sort of if-condition I can put? Right now, I'm getting something like this: `http://www.localhost/` ...

Accepted Answer

`RewriteCond` is already your "if-condition". Just add another one:

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