The Http and the Web | Http Explained | Request-Response Cycle

In this video I talk about the HTTP and how it works on the web, I explain the request response cycle and how http messages make that possible.I also talk about the http message, the start line, headers and body.
I hope you find this video useful! ^^

Hello, nice video. But some corrections / constructive critisism. HTTP is stateless, but not connectionless as you say in the video. HTTP uses TCP for the underlying connection:
"Transport Layer: TCP is a connection-oriented transport protocol. UDP is connectionless."
So actually the client does NOT disconnect after it has sent the request, it will keep the connection open until it receives the response, then it disconnects. No state is kept for this HTTP transaction, this is why it is called stateless. Any new HTTP request will cause a new TCP connection.
Of course this is a simplification, in the real world this would be very inefficient, so web servers make use of Keep-alives to enable reusing the same TCP connection for multiple requests.

In this video I tried to talk just in the application layer. thanks for the clarification ^^

[@dipsmoke]

"At the application layer, HTTP is connectionless. However, HTTP requires a connection oriented service to operate, and that is where TCP comes into play". In other words you can't just say wether its connection less or connection oriented without further explanation of your statement. And basically both of them can be true, depending on the explanation.

[@MR2SpyerJournal]

With understanding of the OSI reference model, he isn't wrong. This is helpful for me as a beginner to make it less complicated. Obviously there is some connection on some level of the OSI model IP/TCP model.

[@xuxamelo]

OSI model is composed of 7 layers however the "TCP/IP" stack is composed of 5 layers. The OSI model it is a "standard" it is not meant to be built. it describes a standard. TCP/IP it was built by the OSI model standard... thought ;)

this video more works for java script programmers than any body else does. specially in about 4:41 timeline you can see title of a java script program syntax. i.e i used java script as an application program for a while it's suggested by web-programmers

[@tyrisnolam]

a thumbs up well spent

[@Leonardo-jv1ls]

To understand how this things works is just think about a client/waiter/cooker relationship. All of them apply the same concept.
