问题
I'm in the process of moving a site to ColdFusion 2016 on Linux/Apache, but one issue we have is the CGI.REDIRECT_URL value is empty. I checked and the following was in the /etc/apache2/mod_jk.conf file:
JkEnvVar REDIRECT_URL
It exists, but it's empty.
I couldn't find much on the web to help except this article, but its already setup like that. Vivio thought 2016 had the redirect_url in the request scope, but that's empty as well.
