Say I wanted to set up a Input Request Header as I'm calling it, I want to set up a server that needs to be visited in order to set a UID, and Token, good for an time limit before redirecting to the website that won't be accessible unless you visit the Input Request Header Server and click the button that sends the request.
What I want the requests to look like is:
GET / HTTP 2.2
Host: IRH.domain.com
IRH-Token: (__input__)
IRH-UID: (__input__)
and have the website set to Status code 400 if request doesn't have an approved Token and UID matched in the IRH server
How would I go about setting my own headers, and how would I set up a page that handles them?
