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.

I've been reading about HTTP headers and it wasn't clicking for me. Found this video and it all makes sense now! Thank you so much!

Hi Tech Cave,
The technical explanation in the video are really clear and understandable just like a story and hence simplifying the process of the learning technical stuffs
Just one request, can you please keep uploading more technical videos .It would be really helpful !!

Every educational video should be like this: concise and insightful. It is difficult to find videos like this.

[manojjustmanoj]

This is a crystal clear explanation for beginners like me

[RussellTeapot]

fantastic explanation! concise yet thorough enough, and most importantly, clearly presented. thank you very much

[MajdyCalisthenics]

this explanation was the most usefull one for me! thanks!

Thank you for the informative video. I have however a question regarding the connectionless nature of http as per your explanation. Since HTTP/S runs on top of TCP 80 / 443 which is a connection-oriented protocol, why then is HTTP considered connectionless?

[Leonardo-jvls]

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

Great Video! To claify, HTTP is a format to send data via the internet to other computers. Is this a good way to summarize it?

[ontologie]

very nice explanation, many thanks dude.

[kyi]

Thank you so much indeed sir. It is real helpful lessons for me.

[joshuaf.]

You mentioned there are some good books out there on this topic. Can you suggest some?

[arthurqa]

hey thank you for the video!!, it is very summed up and it works for a brush up for networking purposes, hope that you get more like later on!!

[sanjitpaul]

You have created a clear immage of http. Thanks Sir.

[Myfriendmrlack]

Can you explain a little more specifically and detailed how the http message gets from your computer to the service and back? For instance, does you browser run methods that invoke your OS to send it to your modem which runs code to send it to some service center that then runs code to send it to the server and then repeats the process all the way back and read again by your browser? How are all these things authenticated? This is just my guess but I've never seen it explained in that type of detail

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
