> If your html isn't long enough, and that abomination still exists, you'll get Microsoft's 404 instead of your nice and short 404. The most annoying part is that this knowledge was abused to make even the most basic and otherwise-useless 404 pages show up in IE. Back when this was a thing, I literally saw this happen. I have one of these pages saved, which is how I know - it was a page which just had "Not Found - The requested document was not found on this server." on it (along with the site name), and then a long HTML comment saying 'Unfortunately, Microsoft has added a clever new "feature" to Internet Explorer.' and explaining the comment's existence. All for a 404 page that gave far less useful information than IE's own 404 page did. If the page had any brand styling on it I might understand, but this was literally a bare-bones, no-styling page with nothing useful on it.
