SPDY is an open networking protocol developed primarily at Google for transporting web content to help
make web pages load faster and reduce latency. HTTP/2 is based on SPDY and is the second major
revision of the Hypertext Transfer Protocol, the application protocol for the Word Wide Web. While SPDY
is enabled by default for all customers using SSL on their site through Cloudflare, HTTP/2 is only enabled
by default for customers of the Free and Pro plan and needs to be enabled under the "Network" application
for all other customers.
