I can point subdomains to subfolders, but not sub-subfolders

I can point subdomains to subfolders, but not sub-subfolders. How can I?

RewriteEngine on


# Rewrite <subdomain>.example.com/<path> to example.com/<subdomain>/<path>
#
# Skip rewrite if no hostname or if subdomain is www
RewriteCond %{HTTP_HOST} .
RewriteCond %{HTTP_HOST} !^www\. [NC]
# Extract (required) subdomain (%1), and first path element (%3), discard port number if present (%2)
RewriteCond %{HTTP_HOST}<>%{REQUEST_URI} ^([^.]+)\.hostingz\.org(:80)?<>/([^/]*) [NC]
# Rewrite only when subdomain not equal to first path element (prevents mod_rewrite recursion)
RewriteCond %1<>%3 !^(.*)<>\1$ [NC]
# Rewrite to /subdomain/path
RewriteRule ^(.*) /%1/$1 [L]

What that code does is redirect http://subdomain.hostingz.org to http://hostingz.org/subdomain. And it works!

But how do I modify the last line, the RewriteRule so that it redirects to sites/(then the subdomain).

So http://subdomain.hostingz.org --> http://hostingz.org/sites/subdomain.

How can it be done? And test it out first as the examples below do not work.

RewriteRule sites/^(.*) /%1/$1 [L]

or

 RewriteRule sites^(.*) /sites/%1/$1 [L]

RewriteRule ^(.*) /sites/%1/$1 [L]

[cont911]

try this:

RewriteEngine On
RewriteRule ^www\.hostingz\.org.*$ - [L]
RewriteRule ^(.*)\.hostingz.org(.*)$ http:\\hostingz.org\sites\$1$2 [L]

Doesn't work.
I found a solution here.

[alter-ego]

If you don't mind my asking, why would you want to have a sub-subdomain? I've never heard of this until now hence my query.

My apologies if I'm missing the point.

I'm not on about sub-subdomains because that's silly. You're right.

I'm instead on about sub-sub folders. The htaccess code I originally had only worked with subfolders which resided in the root directory.
The solution hyperlink which I posted on my post above solves this problem.
