Standardising the “URL”

You'd think that the concept of "a URL" would be pretty clearly defined by now, with the internet being what it is today. Well, turns out -- it isn't.

But Daniel Stenberg, from curl fame, is trying to fix that.

This document is an attempt to describe where and how RFC 3986 (86), RFC 3987 (87) and the WHATWG URL Specification (TWUS) differ. This might be useful input when trying to interop with URLs on the modern Internet.

This document focuses on network-using URL schemes (http, https, ftp, etc) as well as 'file'.

What really strikes me as odd is the interoperability comparison for each "fragment" in the URL;

Component Value Known interop issues exist
scheme http no
divider :// YES
userinfo user:password YES
hostname YES
port number 80 YES
path index.html YES
fragment top no

It's amazing a "URL" even works.

I've said it before and I'll say it again: the internet is held together with duct tape. I hope this proposal gets somewhere, it'll make parsing URLs a whole lot easier and more reliable.
