In addition to Cloudflare's core Performance and Security capabilities,
Cloudflare's network service also includes Websockets support
for all customers.
Cloudflare will accelerate your WebSockets app with a large global content
delivery network, enhance reliability with DDoS protection and increase
security with our IP and Web application firewall. Check out our
plans page for more information.
WebSockets represents a giant leap for real-time web applications
with features like social feeds, multimedia chat, collaborative editing,
multi-player gaming, stock updates, and more.
Standardized by the IETF as RFC 6455
in 2011, WebSockets is a protocol that provides full-duplex,
over a single TCP port.
Because WebSockets creates a single connection and doesn’t need multiple
HTTP headers, WebSockets can provide anywhere from 500:1 to a 1000:1
reduction in unnecessary HTTP header traffic compared to HTTP polling
The server no longer needs to wait for a request to come back before it
sends new data; it can simply push the data to the client the moment it
has new information. Tests have shown a 3:1 reduction in latency compared
to polling solutions.
For more technical information on the WebSockets, you can read up on the
HTML5 Web Sockets Specification.
Cloudflare offers real-time protection against attacks vulnerabilities
including cross site scripting attacks, SQL injections, comment spam,
excessive bot crawling, to email harvesters, and more.
