Please see the below Image, all the requests were sent to the same server almost at the same time.
Chrome version is 86.0.4240.183.
That's very weird, I thought there was a maximum of six TCP connections per host. In my opinion, how the requests were sent should be like the below Image
How could Chrome not to block/stall when making multiple requests, can anybody help?
It's one of the benefits of HTTP/2 that is called multiplexing.
HTTP/1.1 is sort of like buying a single item at a grocery store, taking it back home, going back to the store for the next item you need, and repeating until your pantry is fully stocked. Multiplexing gives you a shopping cart so you can pick up everything you need in one trip.
