Google recently released Google Chrome 21 in the beta channel with support for Webcams and Gamepads. However, another important feature that Google has been working on is the introduction of SPDY (pronounced as Speedy) in the HTTP/2.0 specification. The SPDY protocol has gained a lot of momentum with Facebook committing to support the protocol yesterday and several other big players including Twitter and browsers such as Firefox 13 supporting it as well.
Google has been working on the SPDY protocol since 2009, with it being included in the HTTP/2.0 specifications in January 2012. Since then, several contributors have worked to release newer versions of the protocol with the latest being an experimental release dubbed SPDY/3. Google has also been testing the SPDY protocol on mobile as well. While the goal of the SPDY protocol is to speed up the web, it is up to websites and browsers to implement of the protocol.
However, it looks like two of the major browsers including Firefox and Google Chrome are already working on supporting the SPDY/3 protocol. While the SPDY/3 protocol is restricted to Sandbox builds of Firefox. Google Chrome dev and canary build versions also support SPDY/3 through a switch in about:flags. The support for SPDY/3 is available on Windows, Linux, Mac OS X and Google Chrome OS.
The SPDY protocol is definitely a step towards the future of the web and with major browser support it could help speed up how we access content on the web. Right now, other major browser like Internet Explorer, Safari and Opera do not support SPDY, but hopefully they should do it in newer versions of their browser.
