Railgun with HydronHosting

What is Railgun?

Railgun ensures that the connection between your origin server and the Cloudflare network is as fast as possible.

Railgun compresses previously uncacheable web objects up to 99.6% by leveraging techniques similar to those used in the compression of high-quality video. This results in an average 200% additional performance increase.

How It Works

When a request is made to a Cloudflare server for a web page that is not in cache Cloudflare makes an HTTP connection to the origin server to request the page. It’s that HTTP connection that Railgun accelerates and secures.

With Railgun

Railgun consists of two software components: the Listener and Sender. The Railgun Listener is installed at your web host on an origin server. It’s a small piece of software that runs on a our server and services requests from Cloudflare using the encrypted, binary Railgun protocol.

The Railgun Sender is installed in all Cloudflare data centers around the world and maintains connections with Railgun Listeners.

When an HTTP request comes in that must be handled by an origin server, Cloudflare determines whether it is destined for a Railgun-enabled website. If not, standard HTTP is used, but if so the HTTP request is routed to the Railgun Sender for handling.

Railgun uses a new caching mechanism based on comparing page versions to determine what needs to be transmitted across the Internet to the Railgun Sender. Using this mechanism Cloudflare is able to achieve typical 99.6% compression (taking, for example, a 100k web page down to 400 bytes) and a speedup of over 700%. In fact, the compressed data is often so small that using the binary Railgun protocol the entire response fits inside a single TCP packet.
