HTTP, the protocol of the web, is unencrypted by default. That means it is trivial for someone using the same local network as you to spy on all the data you send to and receive from most websites.
In 2009, Google began work on a new network protocol to make web pages faster. Dubbed SPDY (pronounced "speedy"), the protocol is designed to solve many of the bottlenecks that slow HTTP down. Beginning today, we're rolling out a beta of SPDY to CloudFlare customers.
Transmission Control Protocol (TCP) is one of the primary protocols of the Internet. When you request a web page, the server responds with the data that makes up that page. The data is subdivided into discrete packets of data as they are sent across the Internet.
