How HTTP/2 Works, Performance, Pros & Cons and More
HTTP/2 or H2 for short is a major revision of the hyper text transfer protocol that improves the performance of the web. It uses a binary protocol and multiplexing.
Time codes
0:00 Intro
2:15 HTTP 1.1
5:50 HTTP/2
8/25 HTTP/2 With Push
9:48 HTTP/2 Pros
14:10 HTTP/2 Cons
17:15 Demo
In this video I want to go through how HTTP/2 works, its pros and cons and show the performance difference between HTTP 1.1 and HTTP/2
Http/1
request has to wait for a response
And if you used up your connection response you can send anything else.

So hack !
6 tcp connections
Pros
One connection
Multipex
Push ( have to enable)
Hpack (compress)
Cons
Abuse push
Proxies that dont support it might slow down
Load balancer layer 7 (a layer 7 load balancer that doesnt support h2 will slow down when your web server supports it)
