Status:Base
Module:mod_env

The internal environment variables set by this directive are set after most early request processing directives are run, such as access control and URI-to-filename mapping. If the environment variable you're setting is meant as input into this early phase of processing such as the RewriteRule directive, you should instead set the environment variable with SetEnvIf.

Context:server config, virtual host, directory, .htaccess
