Domain name in mod_rewrite RewriteRule

Question

The task is to get referer domain and send it to my script by RewriteRule. My decision is

SetEnvIf Referer "^https?://(.*)/" myref=$1
RewriteRule ^(.*)$ script.php?referer=%{ENV:myref}

It works right but I wonder if there are any ways to do it (perhaps with RewriteCond)?

Answer 1

mod_rewrite has a variable named %{HTTP_REFERER}. It contains what you expect. You can use it like this:

RewriteCond %{REQUEST_URI} !^/script\.php$
RewriteRule ^ script.php?referer=%{HTTP_REFERER} [L]

See the documentation for more information.
