Notice: Unknown: Skipping numeric key 404

This lead me to rename my variable to $_SESSION['url404'], which would stay set on the redirect.  I have not found any documentation that says that numeric keys are illegal for sessions vars, but I believe it to be the case.

Hope this saves you time in your PHP coding.
