http - client server - request response - connection

Question

I've been reading about HTTP protocol. The description says, "HTTP functions as a request-response protocol in the client-server computing model".

So, my question is, "should Client-Server model always follow Request-Response Protocol? and the vice-versa is true?"

thanks!

Answer 1

Can servers request a response from a client? Well.. no.. I mean.. maybe. But that would contradict the definition of the server and client relationship.

Of course there are acknowledgements - for when a packet is recieved - that the client sends the server, but that's at the TCP level.

At least that's my understanding.
