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

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.

[@TheTechCave]

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 ;)

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!

[@TheTechCave]

Almost Six years since I uploaded this video! I just want to say thank you for all of you! This makes me feel nostalgic. I couldn't focus solely on the channel during this time, but hopefully, I'll come back stronger this time. Support me by liking, sharing, and subscribing. Also you support the The TechCave via ko-fi.com/thetechcave

[@jonas7438]

My professor linked your video in his course at university :D

[@manojjustmanoj1297]

This is a crystal clear explanation for beginners like me

[@seeboonsoo]

Best video ever to explain HTTP protocol. Thanks.

[@attiqahmad7160]

Really impressive.....the way you divided the whole tutorial..thats amazing and at the the summary...MAY GOD SHOWER YOU WITH MORE KNOWLEDGE

[@ivandariopenalozarojas5077]

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

[@Berjoujii]

Great video. one suggestion: try using a bright text color when using a dark background. thanks for the clear and simple explanation

[@MajdyCalisthenics]

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

[@latikacoder]

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 !!

[@RussellTeapot]

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

[@Leonardo-jv1ls]

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

[@wmegamo6879]

Cook, not cooker

[@antonielojeda5476]

True, like an AutoMac

[@mahditeymuri5650]

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

[@proalexv]

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?

[@joshuaf.5398]

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

[@LiEnby]

1:24 ? wtf no- the client stays connected until the server has the response ready and then it connects and sends it the response and only after its sent the response from the server does it disconnect .. it is re-established again for the next request (at least in http1.1, http2.0 is different)

[@sanjitpaul2953]

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

[@ontologie8667]

very nice explanation, many thanks dude.

[@kyi3234]

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

[@Arganoid]

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.

[@ap6471]

You really ought to consider a Patreon. You've got great content.

[@ycombinator765]

everything aside, your voice is on another level. I don't know but I am in love with it!

[@Criteria12]

you have a little mistake. the request and response happens in the same connection the client:- 1- open a connection to server 2- send request The server:- 1- accept connection 2-accept request 3- send response 4- close the connection

[@mohsenmadi3590]

Sounds so correct. This is what I always knew of until the video confused me actually. No such thing as connect-to-server, close, connect-to-client, close. It's only a connect-to-server, do things, send back response, close. Here: en.wikipedia.org/wiki/HTTP_persistent_connection

[@ZzBiazZ]

Wow, your content is great !! Thank you so much dude ^^

[@affy2255]

[@edwardkasimir8016]

this video begins at 0:33

[@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

[@wemode2998]

Felt very comprehensive. Thanks !

[@nobody-ho4rh]

brother please make some videos on cookies also . i want to understand them

[@donpagnotta]

Wait. Isn't the URI in the Start Line of the HTTP Message actually a URN?

[@nixes1636]

Your videos are so great. Hope you make more.

[@srb1855]

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?

[@fadyaldhaim4766]

the video is bullshit

Just amazing video on HTTP :)

[@manishasharma-xz9tx]

sir I have one query about when client disconnected from the server then how can server re- establish the connection...how server knows about the request

[@manishasharma-xz9tx]

plz rply sir 😯

[@TheTechCave]

Hey manisha! I'm sorry for the late reply. After a request is made, the server receives all the required data about the client to operate an send back the response. When the client receives the response, the disconnection happens in the application layer. On the low levels, nothing gets really disconnected. The server knows about thanks to the TCP layer. I hope this helps. And Sorry for my late reply again!

[@blackmouthblackface]

Good pick up, this is a mistake in the slide. The client waits for the response before disconnecting from the server because otherwise how would the server know who to deliver the response to, and if it did this would not be 'connectionless'

[@frankrye3009]

Definitely learnt something here. Thanks a lot!!!

[@ricen0odle118]

finally a video that explains this well, thx

[@UsefulProgrammer]

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?

[@TheTechCave]

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.

Http is stateless not connectionless. As it uses TCP it couldn’t be connectionless.

Thanks for great video. But can someone in here tell me the header or body is required? what would happen if I did not put header or data to the body of http request? What is the require fields for header?

Hey I read that TCP is connection oriented but here http is connectionless and if it TCP based ...then how is it possible?

[@TheTechCave]

HTTP is connectionless only on the application level. HTTP is just an abstraction over TCP. Connectionless here is related to the statelessness of the protocol.

[@PK-db9qj]
