I don't think you can expect that environment variable to be defined.
Maybe you want to switch the value argument to use expr= syntax
instead so you can use more built-in values.

If the request has been internally redirected, all of the original
environment variables from before the internal redirect are prefixed
with REDIRECT_
One example of an internal redirect is the result of rewriterule in
htaccess w/o [R] flag.
