A New Version of HTTP: HTTP/2

February 25, 2015

One of the biggest changes, internet will face in this decade is all set to be launched.  A new version of the HTTP protocol was recently published as a draft by the Internet Engineering Task Force (IETF) – the organization in charge of creating standards for the internet. HTTP/1.1, in use since 1999, will eventually be replaced by a new one, dubbed HTTP/2. This update will improve the way browsers and servers communicate, allowing for faster transfer of information while reducing the amount of bandwidth needed and will make use of secure connections easier.


HTTP/2 is based in part on an earlier protocol called SPDY (read speedy) from Google, and takes most of its speed improvements from it. With the advancement in web technologies, browser has to make several connections for transferring data. This puts a lot of load on both, the server, and the browser. HTTP/2 aims to provide a simpler and cleaner connection among various other improvements.

In the earlier version of HTTP, only one data request can be handled at a time, even though every time you visit a website, you start from four to eight TCP/IP connections. With HTTP/2, each website only gets one TCP/IP connection, but you can have multiple data requests being dealt with simultaneously. The exact number of parallel streams is determined by your web browser. The net result is a faster, cleaner data connection.

Google has announced that it will switch to HTTP/2 in Chrome soon.
