What distinguishes the HTTP/2 protocol from HTTP/1.1 in terms of implementation and performance?

Answer from AI
HTTP/2 differs from HTTP/1.1 in several key aspects that affect implementation and performance:
-
Multiplexing: HTTP/2 allows multiple requests and responses to be sent simultaneously over a single TCP connection, reducing latency and improving channel utilization. In HTTP/1.1, requests are processed sequentially or with pipelining limitations.
-
Binary protocol: HTTP/2 uses a binary data format instead of text, simplifying parsing and reducing error chances.
-
Header compression: HTTP/2 employs header compression (HPACK), decreasing the amount of data transmitted and speeding up communication.
-
Stream prioritization: allows clients to specify request priorities, enhancing responsiveness.
-
Server push: the server can proactively send resources to the client without explicit requests, speeding up page load times.
Ultimately, HTTP/2 provides more efficient use of network resources and improved performance compared to HTTP/1.1.
