Can you list the key differences and features of the HTTP/2 protocol compared to HTTP/1.1?

HTTP/2 significantly improves HTTP/1.1 by introducing several key features:

• Multiplexing — allows multiple requests and responses to be sent simultaneously over a single TCP connection, reducing latency.

• Header compression (HPACK) — reduces the amount of data transmitted by efficiently compressing HTTP headers.

• Stream prioritization — the client can specify priorities for requests so that the server can prioritize more important ones.

• Server push — the server can proactively send resources to the client without explicit requests, speeding up page load times.

• Binary protocol — unlike the text-based HTTP/1.1, HTTP/2 uses a binary format, which simplifies parsing and improves performance.

These improvements make HTTP/2 more efficient, especially for modern web applications with a large number of resources.
