In September 2016, AWS announced that they now support HTTP/2. Īs the speed is the main focus it’s especially important for CDNs to support it.WireShark has support for it but Fiddler doesn’t.There will be a negotiation process between the client and server to select which version to use.The protocol doesn’t have built-in encryption but currently Firefox, Internet Explorer, Safari, and Chrome agree that HTTPS is required.This way it can automatically start sending assets before the browser parses the HTML and sends a request for each of them (images, JavaScript, CSS etc) Allows servers push responses to browser caches.It can use one connection for multiple requests.The problem it is addressing is HTTP requiring a TCP connection per request.so it is backwards-compatible and the main focus is on performance It uses same methods, status codes etc.
It’s based on SPDY (a protocol developed by Google, currently deprecated).HTTP/2 is a major update to the HTTP 1.x protocol and I decided to spare some time to have a general idea what it is all about:
