SPDY is the network protocol. This technology uses the HTTP protocol and many other optimization technologies to make the websites to load faster. It is an open source, TCP based application layer protocol used for transporting the contents over the web. It augments HTTP with several speed-related features to reduce the page load time dramatically. It can allow multiple, simultaneous requests over a single connection and prevents low-priority resources from blocking higher-priority resources. It also allows the server to make efficient use of unutilized bandwidth.
