HTTP/2 is changing the definition of internet world. HTTP/2 allows more efficient utilization of network resources. Day by day web is getting faster. Big round applaud goes to HTTP/2. It provides a reduced perception of latency by header field compression and enables multiple simultaneous exchanges on the same connection.
Some More Words for HTTP/2
HTTP/2 is based on Google’s SPDY which is an open networking protocol developed at Google for transmitting web content. SPDY translates HTTP traffic with reduce web page load latency and improved web security. HTTP/2 makes the Web faster with cheaper requests via multiplexing messages simultaneously, header compression, and reducing server and network load.
What’s the difference?
HTTP/2 encompasses new ways of transmitting data between the web browser and server across internet. It uses same technologies of HTTP1.1 but it is more reliable and allows servers to acknowledge with more content. Browsers can ask for more data from one site and request data from several websites at a time. HTTP/2 speeds up the load process for single or multiple websites. It will allow webpages and browsers to get benefits of the increased bandwidth.
As compare to HTTP1.1 , new version load web pages quickly. Ultra modern web sites which have lots of graphic, text, images and data could load faster. This is beneficial for first time when website is loaded, but after caching on computer it won’t have any affect for subsequent event.
New protocol is also beneficial for mobile browsing. Allowing mobile browser to request more than one item at a same time which cut load times considerably.
HTTP/2 is designed to use fewer connections, so servers and networks will enjoy less load.
HTTP/2 allows the use of a single connection per host, and encourages sites to consolidate their content on one host where possible.
As user’s point of view there is no alteration except speed. Website address bar still shows but at back end it will automatically switch between HTTP1.1 and HTTP/2 as required. It doesn’t mean that HTTP/2 is providing new methods but it is using same library as HTTP/1 with some enhancement. These updates support for HTTP/2 without changing any application code.
Chrome users have been using SPDY protocols with Google services . SPDY transports HTTP traffic by reducing web page load latency and improve web security.
HTTP/1 request has become more expensive which has given rise to techniques like inlining, concatenation and spiriting to decrease the no of requests on a page. But in HTTP/2, these methods shouldn’t be necessary because it already cut down marginal overhead of new requests.
HTTP/2 adds multiplexing technology to allow messages to be interleaved together at same time. One large response which take time to analyze will not block others. HTTP/2’s header compression don’t absorb bandwidth even request is very small.
A question arise for HTTPS
Banks, shops, email and other services will use same secure version of web that is HTTPS. The encryption of HTTP/2 will have same as HTTP1.1 does. It requires an enhanced version of transport layer security TLS1.2 which was standardized in 2008.
When it will publish
The HTTP/2 has been approved by the Internet Engineering task Force and will be published soon.
Developers of SPDY have been also involved in development of HTTP/2. Recently Google has announced final confirmation of HTTP/2 standard would be deprecated SPDY, and support for SPDY will be eliminated in coming year. It is likely that high profile websites like Google, Twitter, Facebook, WordPress and Yahoo will be implementing HTTP/2 in the near future. Chrome and Firefox are already encouraging HTTP/2 and Google is encouraging other browser vendors to have their support for this version.
