I'm getting the above error message.
I have a CF app that uses application.cfc - users access the app with a DNS name - myapp.usps.gov It currently is on a Win2008 server with Websphere - all works fine. I migrated the CF app to a Win2016 server using Tomcat - just trying to access the login page gives me the error message: Variable SESSION is Undefined. So the call is failing at the application.cfc level. FYI - if you use the IP address in the URL instead of the DNS name, all works well. Another FYI - I have another app that uses application.cfm, and calling it with DNS name works fine on same platform. Any suggestions as where to look at in the application.cfc file would be helpful.
