Explanation & Hint: HTTP 1.1 loads resources one at a time in each GET and RESPOND cycle. If one resource cannot be loaded, the rest of the resources cannot be loaded. HTTP 2.0 multiplexes the GET/RESPOND process so that a web client can send multiple GET messages simultaneously. This multiplexing contributes to performance improvement. Both HTTP 1.1 and 2.0 use TCP, compress HTTP messages and use tokens as a mechanism to track web sessions. |
