SPDY is a Google developed protocol designed to deliver website content both faster and more securely. While SPDY is available with your A2 Hosting account, Google has announced SPDY will be replaced by HTTP/2.

Instead you can easily designate portions of your page to be cached (or not cached) with ESI. This is significant especially for sites created by applications like Magento or WordPress.

WebSocket's create two-way interaction between a browser and a website possible for a realtime web experience.
