Hi. I have some experience with PL/SQL and PSP, but I've never used APEX till now (testing 18.2).
We use CAS to authenticate, so I need to pass parameters to the apex application with CAS user and session (obviously, not in the url).
And I need that apex uses those parameters to call a PL/SQL function that checks if they are valid.
If the parameters aren't set it must redirect the user to the CAS page.
If the parameters aren't valid it must show an error and expell the user out of the application.
Can anyone explain how to do that?
