Tim Berners-Lee Is Sorry About the Slashes

Stony Stevenson writes "A light has been shone on one of the great mysteries of the internet. What is the point of the two forward slashes that sit directly in front of the 'www' in every internet website address? The answer, according to Tim Berners-Lee, who had an important role in the creation of the web, is that there isn't one. Berners-Lee revisited that design decision during a recent talk with Paul Mohr of the NY Times when Mohr asked if he would do any differently, given the chance. 'Look at all the paper and trees, he said, that could have been saved if people had not had to write or type out those slashes on paper over the years — not to mention the human labor and time spent typing those two keystrokes countless millions of times in browser address boxes.'"

    From technical point of view, *not* having the // could create problems more easily. For example if you include port number in the URL and browser or program tries to look at what protocol it is based on value before first :

    http://tech.slashdot.org:80/story/09/10/14/1219215/Tim-Berners-Lee-Is-Sorry-About-the-Slashes
    http:tech.slashdot.org:80/story/09/10/14/1219215/Tim-Berners-Lee-Is-Sorry-About-the-Slashes
    Now if you dont write that http: in browser:
    tech.slashdot.org:80/story/09/10/14/1219215/Tim-Berners-Lee-Is-Sorry-About-the-Slashes

    Now the browser would think the protocol is tech.slashdot.org and tries to pass it to a responsible program instead of loading it. This means you would now need to actually type in the http: which none of us do now. Or dropping general URI support from browsers and IM windows and any other programs (you know all those irc:// spotify: and so on URI's). Or then typing in the :80 would be mandatory.

      Or just use a different punctuation character for ports. If you think about how the design of URLs could have been better, other decisions are not cast in stone. The ':' also clashes with the separator in IPv6 addresses (which is an oversight on part of those who designed IPv6).

      http:org/slashdot/tech/story/... (use SRV record)
      http:[org.slashdot;8080]/story/... (use hostname and port)
      http:[123.45.67.8;8080]/foo/... (use IPv4 address)
      http:[2F00:BABA::1;8888]/bar/... (use IPv6 address)
      http:[47.0012.3400.0000.006F.7123.8f23.4012.0c80.0000.00]/ha/... (just kidding)

      This is why I always wanted www to be replaced by web. Just imaging saying web.foobar.com instead of www.foobar.com. How many hours of speech would be saved?

  2. So Who's Apologizing for 'ttp' ? by eldavojohn · · Score: 4, Interesting

    Doesn't the same logic hold for the person that decided it should be 'http' for hypertext transfer protocol and not just simply 'h'? Yes, http is more descriptive but unnecessary. Had another protocol came along starting with 'h' they could have opted for another letter or -- if they were all taken -- became a two letter protocol. I mean, if we're going to get into pedantic apologies for lack of brevity I would assume the three unnecessary letters in http are a greater crime than the double slashes, right? Of course, rarely do I find myself typing anything other than the domain and TLD (i.e. slashdot.org, mail.google.com, woot.com) so this has really become a non-issue.

  3. I thought there was a point to the two slashes by magloca · · Score: 4, Interesting

    Back when I wrote a thesis on dissemination of company-internal information via the world-wide web, in 1994 or so, I remember stating that originally, an indication of which network protocol to use was meant to go between the slashes. But since, in the real world, the network protocol was always TCP/IP, this was made the default and whatever was once put between the slashes was dropped.

    Of course, I don't remember the source or anything.

    I'm pretty sure they are sorry about that. I can't remember who it was, Paul Allen maybe? But one of the early MS programmers said once that he hugely regretted using / for switches in DOS 1.0. When they added directories in a later version, / was already taken so they had to use \ instead.

  5. Re:DNS by alphaseven · · Score: 4, Interesting

    What I wonder is why the designers of DNS put the name in reverse?

    Berners-Lee regrets that as well, from back in 2000...

    I have to say that now I regret that the syntax is so clumsy. I would like http://www.example.com/foo/bar/baz to be just written http:com/example/foo/bar/baz where the client would figure out that www.example.com existed and was the server to contact. But it is too late now. It turned out the shorthand "//www.example.com/foo/bar/baz" is rarely used and so we could dispense with the "//".
