More important feature updates in HTTP2

The HTTP2 specification is not yet fully finalized and some key parts are still being identified. HTTP2 borrowed from Google's spdy ideas.

Although the version number is updated to 2, http1.x is still used in the URL request format, and subsequent versions are updated with a large version number, and no further minor version updates occur.

Compared with http1.x, this HTTP2 has the following important changes:

1, the transfer format is replaced with binary, instead of using plain Text like HTTP 1.x;

2, the connection can be reused (it is not clear whether multiple sessions multiplexing, or multi-application multiplexing), in theory, can significantly reduce the number of requests for connection reconstruction time and resource consumption;

The 3,http header can be compressed and transmitted.

4,server push feature.

For web-based development, there are two main possible impacts:

1, the subsequent request and response time, at the protocol level will be faster, theoretically can properly reduce the difficulty we do the optimization of the front section;

2, the subsequent analysis of network-level problems, is not very convenient (binary transmission, can not be viewed directly), need to use external tools to operate.

In the following Web site, you can find a brief description of the relevant launch background and specifications for the HTTP2 specification:
