That ship has sailed… So many sites don’t actually change pages, they just load different data - it’s way faster and looks better

Problem is, the back button takes you off the site no matter where you are, so now you can change the URL and change the history through code to have the best of both worlds

Then, there’s the people who do it badly, and there’s the people who think “hey, if you need pro StarCraft level clicking speed to back out of my site, maybe for some reason that will make them decide to stay”

As a late millennial and a programmer, I’ve got you.

So when you request a web page, before anything else, the server gives you a 3 digit status code.

100s means you asked for metadata

200s mean it went ok

300s means you need to go somewhere else (like for login, or because we moved things around)

400s mean you messed up

500s mean I messed up

So this is in the 400s. Each specific code means something - you’ve probably seen 404, which means you asked for a page that isn’t there. And maybe 405, which means you’re not allowed to see this

418 means you asked for coffee, but I’m a teapot
