Answer from AI
Main differences between HTTP/2 and HTTP/1.1:
-
Multiplexing: HTTP/2 allows multiple requests and responses to be sent simultaneously over a single TCP connection, reducing latency and increasing performance. In HTTP/1.1, requests are processed sequentially or with limited parallelism.
-
Binary protocol: HTTP/2 uses a binary data format, which simplifies parsing and reduces errors, whereas HTTP/1.1 is a text-based protocol.
-
Header compression: HTTP/2 employs header compression (HPACK), which decreases the amount of data transmitted.
-
Stream prioritization: HTTP/2 allows clients to specify request priorities, optimizing resource loading.
-
Server push support: the server can proactively send resources to the client without explicit requests.
These improvements make HTTP/2 more efficient and faster compared to HTTP/1.1.
