Here at Websavers we are self-professed server and networking geeks, so when we heard about HTTP/2 support being built-in to Plesk – our control panel of choice – we got pretty excited.
Right now, HTTP/1 processes HTML line by line. Each resource is pulled individually, creating dozens – if not hundreds – of web requests for every page loaded. Even though each request is processed in milliseconds, that kind of time adds up pretty quickly when you’re dealing with so many.
HTTP/2 is a bit more ‘intelligent’. It’s been designed from the ground up with the knowledge that websites will have multiple resources. That simply wasn’t the case when HTTP/1 was developed! Additional resources are prepared and ‘pushed’ by the server, and the entire process ends up being much faster.
HTTP/2 is also built around security. It will, in fact, only work over an encrypted channel. Were you waiting for a more compelling reason to get an SSL Certificate (like the free ones we offer through Let’s Encrypt)? Well, now you have one – without an SSL Certificate you’re unable to step into the newest ‘fast lane’.
