How to Get CloudFlare Railgun FREE

Last updated on October 25th, 2018 at 12:22 am.

Being a Cloudflare Optimized Partner, Host My Website Online is excited to offer the Cloudflare Railgun™ technology to all our customers for FREE.

Railgun is Cloudflare’s latest performance optimisation technology that gives you significant improvements in site load times.

CloudFlare Railgun will ensure that the connection between Host My Website Online’s network and the Cloudflare’s network is as quick as possible. Railgun gains a 99.6% compression ratio for previously uncacheable web objects by using methods similar to those used in the compression of high-quality videos. An average website can expect a 1.43x performance boost.

Cloudflare Railgun Introduction How It Works
Cloudflare Railgun Introduction How It Works

When Cloudflare server receives a request for a web page that is not in Cloudflare cache, then Cloudflare will make an HTTP connection to the origin server to request the page. Railgun will accelerate and secures that HTTP connection.

Even Highly Dynamic Websites Change Slowly

CloudFlare Railgun works by understanding that uncacheable web pages do not change very often. For example, during an experiment, the CNN.com homepage HTML was captured once, and then again after 5 minutes and then again after one hour. The page sizes were 92,516, five minutes still 92,516 and one hours later 93,727.

CNN sets the caching on this page to 60 seconds. After one minute, it is necessary to download the entire page again. However, looking inside the page, not much has changed. The change between versions is on the order of 100s of bytes out of almost 100k.

Cloudflare’s experiments have revealed similar change values across the web. For example, reddit.com changes by about 2.15% over five minutes and 3.16% over an hour. The New York Times homepage changes by about 0.6% over five minutes and 3% over an hour. BBC News changes by about 0.4% over five minutes and 2% over an hour.

Although the dynamic web is not cacheable, it is also not changing quickly. That means that from moment to moment there’s only a small change between versions of a page. Cloudflare Railgun uses this fact to obtain very high rates of compression. This technique is very similar to how video compression looks for changes from frame to frame; Railgun seems for changes on a page from download to download.

Cloudflare Railgun Technology

Railgun consists of two components: the sender and the listener. Cloudflare installed the sender at every Cloudflare data centre around the world. The listener is a software component that Host My Website Online has installed on our network for customers. So, you don’t need to install or connect anything to make your website Railgun activated.

The sender and listener establish a permanent TCP connection that’s secured by TLS. Railgun protocol will use this TCP connection. It’s an all binary multiplexing protocol that allows multiple HTTP requests to be run simultaneously and asynchronously across the link. Or in other words, a persistent connection is opened between Cloudflare’s network and ours and eliminates the overhead of TCP.

We have made it simple for our customers to get the advantages of Railgun with one click.
