- 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 ^^
"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.
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.
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 ;)
👍
Really impressive.....the way you divided the whole tutorial..thats amazing and at the the summary...MAY GOD SHOWER YOU WITH MORE KNOWLEDGE
fantastic explanation! concise yet thorough enough, and most importantly, clearly presented. thank you very much
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!
Every educational video should be like this: concise and insightful. It is difficult to find videos like this.
Best video ever to explain HTTP protocol. Thanks.
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 !!
Great video. one suggestion: try using a bright text color when using a dark background. thanks for the clear and simple explanation
Thank you, good explanation of what HTTP is!
This is a crystal clear explanation for beginners like me
Wow, your content is great !! Thank you so much dude ^^
Nice Video! i finally understood how and why Request and Response works Thank You :)
Underrated channel dude. Thanks !
Felt very comprehensive. Thanks !
This video is extremely helpful!! Thank you!
this explanation was the most usefull one for me! thanks!
Thanks m8! A lot of concepts cleared out! :)

Simple and clear, very good. Thank you.
Definitely learnt something here. Thanks a lot!!!
Just amazing video on HTTP :)

Nice explanation, thanks
Hello, this video is very helpful, simple and easily understandable.
Thanks! Great insight!
thanks, great content!
dang, this video's good, thanks for the info
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?
good and informative . providing free information is a nice job
*that was amazing thank you!*
Very well said Sir.
Thank you very much
really excellent video, cheers
Thanks for such great knowledge
To understand how this things works is just think about a client/waiter/cooker relationship. All of them apply the same concept.
Cook, not cooker
True, like an AutoMac
Thank you so much, this is the best explanation of how HTTP works, and I like the way you use the graphics to explain what you are talking about, simple, clear and concise.
Well organized and explained tutorial
I can’t thank u enough!!
Amazing upload more and more vedio good way of teaching .
God bless you .
Keep it up,
From Pakistan 🇵🇰
Really helpful thanks!
brother please make some videos on cookies also . i want to understand them
Thank you sooo much mate !!!
Nice video, thanks!
very clear thank you very much my friend
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
Very well explained thank you
It is an excellent learning video. Thank you teacher for sharing your knowledge!
this is such a great explanation
Thank you!
Nice Video, good explanation
very good....teaching skills
The middle box in the "user case" at 7:41 has been copy/pasted from the request's user case. eg "Host" is not a header parameter in the response.
Good explanation bro
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?
Good pressentation ! could you tell different between http and http200 /http2006 and is it support from C panel host ?
Great Explanation!! (y)
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
Awesome thanks mate
very helpful ,thank you
Thank You So Much !!!
Thanks for this. It's a great start to HTTP, but I'm looking for something a LOT more detailed with practice work. Do you have any suggestions?
You can dive deeper through detailed books like "Restful Web Services" by Richardson and Ruby. In terms of practice, side projects using public APIs or develop your own Complex API.
@@TheTechCave that's nice thanks for this info 🙂
Nice!
Thank you very much
@The TechCave I must say that is a pretty good content to learn. However, I would like understand HTTP thoroughly. Could you please suggest a way to achieve this or even a book would do ?
Thank you in adavance.
Nice video thanks.
It was really helpful👍👍👍
thanks ...great video
everything aside, your voice is on another level. I don't know but I am in love with it!
that's great man soo thanks

Informative.
At start I though what the... But later hey its very informative. Thanks

How does the browser render images for examples? If I have 4 images, does it make 4 http request and render them one after the other if found ? or all at once ?
4 separate http requests.
