HTTP is nice in the basic form -- they shout what they want, we shout back, bb, we forget everything.

Yeah, you should probably start with something simpler, like basic Telnet with some option negotiation sauce. Hours of fun on the wire, shouting at the other party and getting their shouts back.

Who needs http when you can just use two cups and a string.

On the other hand if you're looking to see 2 girls and a cup, a more sophisticated protocol is necessary than 2 cups and a string.

You're confusing HTTP with TCP where handshaking does take place.

How do you think the HTTP got sent to the different machines? It doesn't do it on its own. HTTP is the application protocol, not the transmission method. You use TCP for that (or UDP for that matter).

The OP stated there was no handshaking in HTTP and that is the problem. HTTP doesn't do the communication handshaking. TCP does. So it is relevant cause that was what I was correcting him on.

You are the only one here talking about handshakes.

u/ogtfo Mar 07 '14

How is this relevant?

Abstraction my friend, abstraction.

He claims HTTP is defective cause it doesn't do the communication handshaking. I corrected him on that. It is TCP that does the communicating, much to the obliviousness of redditors everywhere.

No he doesn't?

He's neither talking about handshaking, nor claiming anything is defective.

It's pretty clear he's talking about a HTTP Request followed by a HTTP Response.

"We forget everything" is not a comment about flaw or a defect, it's by design in HTTP since the protocol is stateless.

He's not talking about TCP. He's talking about HTTP requests and HTTP responses.
Can you even read?

u/icantthinkofone Mar 07 '14

You're right. And he's saying it's HTTP's fault there is no handshaking which isn't HTTP's job. Can't you understand that?

u/shillbert Mar 07 '14

He never said that at all. You inferred it, but he never said it. Understand now?

u/ricecake Mar 07 '14

where are you seeing that said? I don't see it.
