IETF had announced that they are officially working on the next version of HTTP – HTTP/2.0.
The current version of HTTP – HTTP/1.1 – had worked very well for the past 13 years since 1999; however, as it was originally designed for the serving of small static pages, the protocol was not optimal for rich and resource intensive web applications. HTTP/2.0 seeks to address this and will use Google-developed SPDY protocol as its basis.
SPDY improves on the existing HTTP protocol through 4 main features:
- Multiplexing multiple HTTP channels through a single (TCP) connection.
- Assignment of priorities to HTTP requests so that the important ones don’t get throttled.
- HTTP headers compression
- Server push/hints
