How to create separate routing for the same URL?

Question

I created a website that, when the user correctly fills out the form, is redirected to the confirmation page with the URL mySite.com \ A \ confirm .

I want to be able to redirect the user to another page. If he enters this url " mySite.com \ A \ confirm "

What is the best way to achieve this (I was hoping for something more elegant than each user's state)

It is better to add a check on the same page, and if the form has not been submitted, simply show the message or throw a 404 error (not found).
