need the name of http_host for a htaccess rewrite condition

Question

I want to write a rule where I don't know the exact http_host.

For example I have (www.)?example.com. Now I need example to build the following:

(www.)?example.com/example/... in a RewriteRule.

So how can I split the http_host into name only?

If you need to get just the domain name, less the TLD. Then you can do something like the following:

RewriteEngine On RewriteCond %{HTTP_HOST} ^(?:www\.)?([a-z-]+)\.com [NC] RewriteRule ^$ /%1/ [R,L] 

Where %1 is just the domain name. eg. example in your example.

This assumes a TLD of .com.
