Relative URLs as //ajaxian.com

Category: HTML, Tip

I had never thought to use relative URLs that are just relative to the protocol scheme as Ned Batchelder explains in his post on Http-https transitions and relative URLs.

Whew knew? Only those who read documentation.

I use this a lot specifically for this purpose of easily making the same content show on both secure and non-secure sites with mixed domains in the URL. Many lame browsers, like old versions of WebTV weren’t written by developers who read the documentation (like Rick points out) don’t support it. Fortunately, if you can get ahold of the developers and point out the RFC, most are willing to fix it, as happened when I contacted a research search engine with a busted mining bot.
