all subdomains go to non .htaccess

linux shared server

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

Open in new window

this is .htaccess code (i hope it is correct)
to have www. redirect to non www

sometimes I type wwwww.example.com or ww.example.com
could I have a rule where all subdomains forward to http://example.com

Two methods. The first assumes that any prefix that is not "www" or "null" is a subdomain. The second requires explicitly listing subdomains as conditions.

Note that neither of these methods preserve query strings. If the site does not use query strings then this is no issue. If the site uses query strings then %{QUERY_STRING} must be appended to the target URL.

Now here is the catch. In order for this to work, the server must be either (a) non-vhost and accept any domain name at all, or (b) a vhost with the possible subdomain names explicitly accepted in the vhost definition. Otherwise the server will reject the request as "not for this site."

RewriteCond %{HTTP_HOST} ^www\.example\.com [NC]
RewriteCond %{HTTP_HOST} ^example\.com [NC]
RewriteRule .* http://example\.com%{REQUEST_URI}

RewriteCond %{HTTP_HOST} ^subdomainfirst\.example\.com [NC,OR]
(continue as required for all subdomains)
RewriteCond %{HTTP_HOST} ^subdomainlast\.example\.com [NC]
RewriteRule .* http://example\.com%{REQUEST_URI}
