Web trivia tangent: When you do a 301 redirect, how long can a browser simply send later requests to the new location without touching the old?

Well, it "permanent" so… unless otherwise specified by cache / expires headers, *forever*

A lot of web software by default doesn't set any of those headers on a 301. So if you redirect x.example to y.example, and then *months later* decide to use x.example for something, people who saw the redirect may just go y.example
