Answer from AI
Main differences between HTTP/1 and HTTP/2:
-
Multiplexing: HTTP/2 allows sending multiple requests and receiving responses simultaneously over a single TCP connection, whereas HTTP/1.1 processes requests sequentially or with limited parallelism.
-
Binary protocol: HTTP/2 uses a binary data format, which simplifies parsing and increases efficiency, unlike the text-based HTTP/1.
-
Header compression: HTTP/2 employs header compression (HPACK), reducing the amount of data transmitted.
-
Prioritization: HTTP/2 supports request priorities, enabling optimization of resource loading.
-
Server push support: HTTP/2 can send resources to the client without explicit requests, speeding up page load times.
These improvements make HTTP/2 more performant and efficient compared to HTTP/1.
