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.
