"RewriteRule ^" means?

This code
Code: Select all
RewriteCond %{HTTP_HOST} !^(www\.) [NC]
RewriteRule ^ http://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]


adds the www. to a domain, but..what does the "^" mean after RewriteRule ?

It is an anchor. It matches the beginning of the URL (or the relative part of the URL). So ^a will match /a but not /1a.

In this case, as there is nothing after the ^, it will match anything (like .*) because there is always something (even an empty string/URL) to match.
