Why can't I redirect www to non-www on my addon domain?

Question

I have a domain example.com in which I'm doing this to redirect all my traffic from www version to non-www:

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

Everything fine until now. I can do www.example.com to example.com, but I also have another domain which I am hosting on the same account as a addon domain. Like there is a folder like example.org in my base www directory of example.com.

Now when I'm doing www.example.org, I get http://example.com/example.org with an additional 404.

Hope you get my point. Thanks in advance.

Answer 1

This occurs because the .htaccess will be inherited in all child directories. This is a common issue when using add-on domains because each domain shares the same path environment.

This can be resolved by any of the following:

• Use more secure hosting with jailed accounts
• Use a .htaccess in each add-on domain child directory
• Use %{HTTP_HOST} ^www.example.com [NC] rather than %{HTTP_HOST} ^www.(.+)$ [NC]
