#www. is overrated
RewriteEngine On
RewriteCond %{HTTP_HOST} ^www\.(.*)
RewriteRule ^(.*) http://%1/$1 [QSA,L,R=301]
Now let’s explain how this works:
The first line is a comment, that explains what the rewrite is supposed to do.
This line just turns on the rewrite engine
RewriteEngine On
This line says if the domain is “www.anything” and note that it saves the domain without the www. part as %1
RewriteCond %{HTTP_HOST} ^www\.(.*)
now this line does the actual rewriting. from anything to the domain with the query string attached (QSA) so we won’t break links. also note that it is a permanent redirect (the R=301 part) and it’s the last rule (L) that will be executed for this request.
RewriteRule ^(.*) http://%1/$1 [QSA,L,R=301]
