OPLIN 4cast #426: The next version of HTTP
February 25th, 2015

Hypertext Transfer ProtocolLast week, the Internet Engineering Steering 
Group (IESG) posted a message 
<https://lists.w3.org/Archives/Public/ietf-http-wg/2015JanMar/0478.html> 
stating that they had "...approved the following document: 'Hypertext 
Transfer Protocol version 2'...as Proposed Standard." While this sounds 
pretty innocuous and/or cryptic to many of us, this announcement 
actually marked the official beginning of HTTP/2, the long-awaited 
successor to HTTP/1.1, the information transfer protocol currently used 
by the World Wide Web (allowing the hypertext linking between web pages 
mentioned in last week's /4cast/). While that still may not mean much to 
most of us, we should all notice that the Web will respond a bit faster 
in the future than it does now, once HTTP/2 becomes the common standard.

  * The internet is about to get faster - here's why
    <http://www.businessinsider.com/the-internet-is-about-to-get-faster--heres-why-2015-2>
    (Business Insider | Peter Maynard) "When a web page is requested,
    the server sends back the page, but must wait for the web browser to
    parse the page's HTML and issue further requests for things it finds
    in the code, such as images. Server push allows the server to send
    all the resources associated with a page when the page is requested,
    without waiting. This will cut a lot of the latency associated with
    web connections. Once web servers and web browsers start
    implementing HTTP/2 - which could be as soon as a few weeks from now
    - the web-browsing experience will feel quicker and more responsive."
  * Everything you need to know about HTTP2
    <http://readwrite.com/2015/02/18/http-update-http2-what-you-need-to-know>
    (ReadWrite | Lauren Orsini) "For the past 16 years, HTTP has
    basically done the heavy lifting of bringing Web pages to your
    browser. When you type a URL into your browser bar-readwrite.com,
    for instance-you're actually creating an HTTP request to the Web
    server that instructs it to find and deliver a particular Web page.
    But HTTP has its limits. Modern Web pages pack in more features than
    just about anyone imagined back in 1999, making it more
    resource-intensive than ever
    <http://httparchive.org/trends.php#bytesTotal&reqTotal> just to load
    them in a browser."
  * HTTP/2 finished, coming to browsers within weeks
    <http://arstechnica.com/information-technology/2015/02/http2-finished-coming-to-browsers-within-weeks/>
    (Ars Technica | Peter Bright) "In HTTP/2, multiple bidirectional
    streams are multiplexed over a single TCP connection. Each stream
    can carry a request/response pair, and multiple requests to a server
    can be made by using multiple streams. However, the streams are all
    independent; if one stream is slow, the HTTP/2 connection can still
    be used to transfer data belonging to other streams. Similarly, a
    client can request a large object and then a small object, and the
    response to the small object can be given before, or even during,
    the response to the large object."
  * Don't blame yourself for ignoring HTTP/2, the biggest HTTP update in
    years
    <http://venturebeat.com/2015/02/18/dont-blame-yourself-for-ignoring-http2-the-biggest-http-update-in-years/>
    (VentureBeat | Cullen Macdonald) "HTTP/2 is for sure going to add to
    the increase in rate of change for things on the Internet, but it'll
    do it without being noticed. It will continue to be incorporated
    into more websites you visit, and browsers will more fully support
    the official spec. There won't ever be an explosion of speed from
    your phone's browser where you'll ask yourself 'oh! is today HTTP/2
    day?!'"
