The following rule in .htaccess

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

when accessing the url of the form

 http://example.com/something

redirect to

 http://www ./something

those. RewriteCond works, but transmits nothing. Someone tell me - what is the mistake here?

Immediately get better - an option with

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

and other similar options work, this is understandable.

    The problem is that when denying, you cannot use $ N or% N. The example above will work if you only use% {HTTP_HOST} directly in the RewriteRule:

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

    This is the answer, actually. The question is closed )
