SPDY

SPDY is an application layer protocol developed by Google based on the Transmission Control Protocol (TCP. Google first proposed the SPDY protocol in Chromium [1]. It has been used in Google Chrome to access Google's SSL encryption service.
SPDY is currently not a standard protocol, but SPDY's development team has begun to promote SPDY to become a formal standard (now the Internet Draft), Google Chrome, Mozilla Firefox, both Opera and Internet Explorer support the SPDY protocol. The SPDY protocol is similar to HTTP, but it is designed to shorten the webpage loading time and improve security. The SPDY protocol reduces the loading time by compressing, multiplexing, and priority. SPDY is not just the abbreviation of "speedy. SPDY is now a trademark of Google.

Design

SPDY is designed to reduce the loading time of webpages. Through priority and multiplexing, SPDY allows you to transmit webpage content, images, and other resources by setting up a TCP connection. SPDY is widely used in TLS encryption, and the transmitted content is also compressed in gzip or DEFLATE format (unlike HTTP, HTTP headers are not compressed ). In addition, in addition to passively waiting for the browser to initiate a request like HTTP, SPDY's web server can also actively push content.

Relationship with HTTP

SPDY is not used to replace HTTP. it only modifies the transmission mode of HTTP requests and responses over the network. This means that you only need to add a SPDY transport layer, no modifications are required for all existing server applications. When transmitted using SPDY, HTTP requests are processed, marked to be simplified, and compressed. For example, each SPDY endpoint keeps track of the HTTP packet header that has been sent in the previous request, so as to avoid repeated headers that have not changed. The data of unsent packets will be compressed and sent.
