It is incorrect to "normalize" // in HTTP URL paths

Brace yourselves: the internet is having a nerd fight over… double slashes. A new explainer says collapsing // to / in a web address isn’t “normalizing” at all — the rules actually allow empty segments, so those two slashes can mean something. Translation: changing // to / can point you to a different place. The Lobsters crowd? Split down the middle and throwing popcorn.

On one side, the spec purists: the standards say hands off, so hands off. On the other, the battle-hardened pragmatists rolling their eyes: “we’ve been folding slashes for decades because real websites are messy.” One commenter likened ignoring this to grammar pedantry — the Oxford comma of URLs — while another called URL handling a “minefield” where every tool disagrees and mapping links to your hard drive only makes the explosions bigger.

Then came the twist: some devs actually use // on purpose as a secret doorway for embedded content that won’t clash with real files. Others warn that fancy theory melts under real-world heat: sites abuse weird URL tricks, and security teams have chopped out double slashes to block old-school exploits. The vibe? Spec vs. Street. And the memes? “Not your filesystem, honey,” and a collective sigh that the web runs on duct tape, vibes, and double slashes.
