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.
