The only one I didn’t know was origin trial; though curiously that line also used http-equiv, which is an interesting one, because those meta tags act can be used in place of response headers (and vice-versa). I was a little surprised that the “perfect answer” didn’t call that out. I’m actually impressed there was quite a lot to discuss in just 10 lines. That said, i’m less convinced it’s worth spending precious interview time on it, but I could be persuaded.
