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