The difference between how HTTP1 handles multiple requests vs how HTTP2 handles the same 😁

👉 In HTTP1, the browser (or any client) needs to establish a new connection with the server for each file it needs to get. This establishment includes the TLS handshake, where server and client exchange secure keys for encrypting the communication.

👉 In HTTP2, this is optimised. The browser can establish a single connection, and make multiple requests through the same connection, in series (one after the another).

This is well suited for web application kind of workloads, where the browser would first get the index.html, and then may want to fetch the scripts and styles that are embedded in them.
