问题
This seems to be a non-issue for many people (read: I can't find an answer), but I would like to update the following htaccess code to not only remove the 'www' from the URL, but also any sub-directories that are accessed.
RewriteEngine on
RewriteCond %{HTTP_HOST} ^www\.(.+)$ [NC]
RewriteRule ^(.*)$ http://%1/$1 [R=301,L]
With this, http://www.example.com/any/ resolves fine, but I want it to redirect to http://example.com/any/ as with the root.

I had the same problem (trouble stripping 'www' from URLs that point to a sub-directory on an add-on domain), but after some trial and error, this seems to work for me:
RewriteEngine on
RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
RewriteRule ^(.*)$ http://%1%{REQUEST_URI} [R=301,QSA,NC,L]
回答2:
Redirection code for both non-www => www and opposite www => non-www. No hardcoding domains and schemes in .htaccess file. So origin domain and http/https version will be preserved.
APACHE 2.4 AND NEWER
NON-WWW => WWW:
RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^ %{REQUEST_SCHEME}://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
WWW => NON-WWW:
RewriteEngine On
RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
RewriteRule ^ %{REQUEST_SCHEME}://%1%{REQUEST_URI} [R=301,L]
Note: not working on Apache 2.2 where %{REQUEST_SCHEME} is not available. For compatibility with Apache 2.2 use code below or replace %{REQUEST_SCHEME} with fixed http/https.
APACHE 2.2 AND NEWER
NON-WWW => WWW:
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^ http://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
RewriteCond %{HTTPS} on
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^ https://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
... or shorter version ...
RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteCond %{HTTPS}s ^on(s)|offs
RewriteRule ^ http%1://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
WWW => NON-WWW:
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
RewriteRule ^ http://%1%{REQUEST_URI} [R=301,L]
RewriteCond %{HTTPS} on
RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
RewriteRule ^ https://%1%{REQUEST_URI} [R=301,L]
... shorter version not possible because %N is available only from last RewriteCond ...

I think you're close, but try the following:
# force non-www domain
RewriteCond %{HTTP_HOST} ^www\.example\.com$ [NC]
RewriteRule (.*) http://example.com/$1 [R=301,L]
Not sure exactly what you mean about sub-directories, but this follows your example.

I used it and it worked for me
RewriteCond %{HTTP_HOST} ^www.locphen.vn/$ [NC]
RewriteRule ^(.*)$ http://locphen.vn/$1 [R=301,L]
Example: http://www.locphen.vn/he-thong-loc-nuoc-gieng.html -> http://locphen.vn/he-thong-loc-nuoc-gieng.html

I use this code. If my visitor does not have www in his url then this condition adds www with url, otherwise no need to add www with url ( because he already has. :) )
RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\.YOUR-SITE\.com$ [NC]
RewriteRule ^(.*) http://www.YOUR-SITE.com/$1 [L,R]

Hello, the code works perfectly, except that it passes with the www in a url with some value and slash at the end it shows the parameter and value in the url.
RewriteEngine On
SetOutputFilter DEFLATE
AddOutputFilterByType DEFLATE text/html text/plain text/xml

RewriteRule ^(.[^.*]+)\/$ ?jogar=$1 [NC]

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