Hyper Text Transfer Protocol Crash Course - HTTP 1.0, 1.1, HTTP/2, HTTP/3
ฝัง
- เผยแพร่เมื่อ 4 มิ.ย. 2024
- HTTP is a protocol for transferring web pages, text, media, binary files and much more. It stands for hyper text transfer protocol and It is what the Internet pretty much runs on. In this video we will learn how HTTP works, how it is secured with HTTPS, will also show how to spin up an Http web server, and we will also go through the evolution of HTTP starting from HTTP 1.0 to HTTP 1.1 to HTTP/2 and eventually HTTP/3 which is still experimental.
Client / server
Client makes HTTP requests to a server that supports HTTP, the server (web server, http server like apache tomcat, nodejs etc..) responds back with the content. This could be an HTML page, images, JSON and much more.

Request (browser, web app)
- URL
- Method type
- Headers
- Body
Response (web server)
- Status code
- Headers
- Body
HTTP 1.0 over tcp
- Application Layer 7
- new connection with each request.
HTTP 1.1 over tcp
- Persisted connection
HTTP/2 over tcp
- Compression
- Multiplexing
- Server Push
- SPDY
- Mostly secure by default
- Negotiates protocol during TLS (NPN/ALPN)
HTTP/2 over QUIC ( HTTP/3)

i dont mean to be so offtopic but does any of you know of a tool to get back into an instagram account..?
I stupidly forgot the login password. I would love any tricks you can offer me
@Ayaan Callan Instablaster :)
@Deacon Jay i really appreciate your reply. I got to the site through google and im trying it out atm.
Takes a while so I will get back to you later when my account password hopefully is recovered.
@Deacon Jay WTF IT REALLY WORKED! I literally hacked my ig login within about 40 minutes by using the site.
I had to pay 15 bucks but for sure worth the price :)
Thanks so much you saved my ass !
@Ayaan Callan Happy to help :D
Please don't make short videos. I like your way of teaching. And these long Videos, really helped me. Thanks.
Thanks ! I do prefer the longer format too where I can discuss the topic in depth
I really dislike people making 2 min videos. I think our attention span is undervalued. We like to study.
Make long in video , which have depth explanation
This youtube channel is gold, all your playlists must be made mandatory for every sw engineer. I can't believe you are doing this for free
Really not that big of a deal
@@rl1491 it is a big deal, this channel is awesome!
So true, this content is gold. Really thankful to him for providing it for free.
Your 45 minute long video is totally cool. Its a whole load of information. Any serious learner would not mind it. So, feel free. We got the attention span. Dont worry. :)
Thanks 🙏 i am glad the long videos are informative
Informative? They are gold man! Really awesome stuff!
Best software channel in youtube in my opinion. Most channels make short videos to hook up beginners, but these topics require a complex and detailed explanation, this is hard stuff. Please keep the videos comming, no matter how long they are. The quality and amount of relevant information is just unbelievable, better than most colleges.
i love rewatching vids after a few months just to see how much my understanding has improved
I'm about to start a co-p term in Web dev, and your videos are both reminding me and teaching me new things relevant, all while being extremely fun. You are amazing Hussein, thank you!
We love your long videos, please keep it up. I've learnt so much in the past few weeks. Thanks for sharing. Means a lot.
The amount of knowledge with the sense of humor with the way you teach it's just FABULOUS, Thaaaaanks a lot for your help
I absolutely love when you talk about something at length.
Your energy is amazing. Thanks for this video!
Thanks for your comment ! Really Appreciate it
I recently just changed career from accounting to SWE. your channel has been an immense help for me. Thank you so much!
I've experienced a lot of emotions while watching your videos and will experience more as I need to study the topic thoroughly, but man you're an amazing educator, thank you so much
Yesterday I was reading on QUIC and HTTP/3 and I wished you made a video on them. Luckily today I am here.
PK CC enjoy the video! Wish granted .. I need to make a specific video on just QUIC.
2021 and this video still fills the gaps about different protocols.
Love your videos... The highlight of your videos is that you interconnect stuff and make the entire area make sense( rather than only focusing on teaching a very specific topic and leaving the user with a bunch of questions on how the topic fits into the bigger picture or with other connected topics) ..... Another great thing is the real life inferences that you draw.. For me this is the right way of learning software engineering..... Amazing stuff. .. Please don't change the format.
Thank you so much for your comment and feedback ❤️
I think all the other channels.. Related to backend.. Just talk about the code in a shell and.. Didnt go deep to how the things works.. Behind the scenes, this channel is a gem, thank u hussein.. For valuable content as always❤
For some reason i really like listening u explain technology...reminds me of science tv shows i watched as a kid 😁
I’m sure you get this all the time, but thank you so much for making these videos and making them free. You’ve helped many people, including myself, find their way through software engineering
Glad to hear that Bryce, its all you. 🙏
Thank you for this video ❤️ I was having issues with my web browser being slow and this doesn't solve my problem, nor do I understand any of it, but it seems very complex and it's impressive you know all of this and are willing to give away the knowledge.
I love your videos!! Please keep making longer videos otherwise it would be impossible to show the content in detail.
I appreciate all your videos, you make technical matter super interesting. I've learnt a lot from you Hussein, keep up the great work!
Thank you man, you are make the best network tutorials on youtube.
Beleive me I searched whole youtube for getting HTTP finally luck did work and found such amazing video That helped me a lot thanks Hussain sir,love from pakistan
Thanks for going in depth and not skimping on key details -- totally worth the longer length
Thanks Juan!
Your content is so awesome, Hussein!
You are really awesome!!! I learn so much stuff from your videos! Because of your very best effort like this, there will be a lot of better engineer and we will make the world better together!
Great video. What an awful mindset I had before I encountered your channel. There is so much to learn
Truly aaaaaaaaaaamazing videoss. This is not long. It is precisely perfect to understand.
Dayum, This is pure Gold!
your video even its long, its entertaining and presents so good info and your voice kept me awake lol thank you so much.
Yes please create a series on HTTP status codes! I am often confused about the right status code to use when writing server-side code
Concepts are elaborated in just plain English 😀 ..A big thumbs up 😀
I love this... Didn't even realise when the 45 minutes passed
I really like the way you teach things. Whereas I feel their are a lot of areas in this video which you touched but didn't explain well. Maybe a part 2 can help me understand it better. But thanks for spreading good knowledge.
Very informative. Thank you. Love the long videos
Amazing video matched with AMAZING energy! Liked AND Subscribed!!!
It's good you are making large video...first time I get addicted in watching your video
I watched the OSI model & TCP/UDP videos by Hussain before this one in a succession.
I definitely feel I understand these concepts a bit better.
I do feel these concepts demand a clear understanding specially from backend devs.
Really cool as always! Thanks
You're such a good teacher. Thank you
Good job, you explain as a pro and i love your channel.
Thank you!
ivan89pln ❤️😊thanks!!
Just awesome Hussein!
🙏🙏❤️
Very well articulated. Thank you so much

Cool way of explanation! Thank youuu!
priceless. thank you so much Hussein.
You always delivers best 😍😍
Very useful review and overview, thanks.
(never apologize to the audience. :-) )
Thanks Boys! Appreciate it 😊
Please keep it long than please the Yutube Algo, I discovered u just today but I've been watching them and they are priceless
I really like making my videos long because I go explore many details. I know most people prefer short videos but I just can’t force myself to. Thanks 🙏
Hussein, 5 seconds into any tutorial: "Hey guys, let me reference a video" 😂
Jokes aside, I love your content, you're hands down the best web dev teacher on YT.
Really appreciate it!!
Very helpful video.
Amazing explanation.
Thank you so much for these videos. They are helping me enjance my software engineering knowledge
Thanks Hussein Nasser, helpful content!
Your videos are great. Thanks for your efforts.
Appreciate it Mohd! H2 is awesome tech
I can't believe that this channel has only 50k subscribers :(
Great job. Awesome video.
Thank you a lot.
Bro you are amazing.. i would have skipped college if i had access to youtube previously
You are such a great guy! Love your videos and your content, and most importantly I wanted to know "Mahn, How do you get me watching the entire video without losing my interest or attention?"
❤️❤️ glad you enjoyed it!
I used to use incognito for something else...
me tooo :)
Thanks for your videos
Keep on doing videos like this
Thank you for a fun and educational video.
Thank you so much, It's Netflix for Backend Developers. :P
Really like the video, ARIGATO for your effort.
This guy is the best! Wow I love him
It's really appreciable stuff thumbs up for you
When someone making a video about HTTP doesn't know the difference between the WWW and the Internet and then proceeds to ask you to "ring that bell".
Social Media / TH-cam learning in a nutshell
Great information, love the presentation
Thanks Sunil 😍
Great content, thank you !!!
Masha Allah, I enjoyed getting this learnt
please never stop making videos
🙏🙏
These videos are awesome!!! Could you please do a nice long video explaining how QUIC works as well?
Yes in the plan 😍
Believe me, you should teach at a university. Thanks a billion
its okay even if your videos are 24 hrs long. These are just great.
Great video, very informative. Can you please do a video on the available options for encryption over UDP, something like what TLS does for TCP. Or if you have already made a video please point me to it. Thanks
I love how you explain everything I am a self taught developer wish I could've found your channel 2 years back. I have a question is there any difference between backend software engineer and backend developer?
they are similar, devs usually write the product code and engineers design, architect and test but thats not set on stones .. for example an engineer role can do all of this
Welcome 🙏 and all the best,
Awesome presentation and explanation . I am from Bangladesh
great video!
This is Gold.
Just one question
How do you design your slides in your videos?
extremely helpful
Thanks for the video sir !!😀
Love this video
ممتاز جداً يا شيخ ناصر استمر نحن متابعينك بشدة. الله يوفقك ورمضان مبارك عليكم
شكرا معاذ على التشجيع ❤️ مبارك عليك الشهر
best channel 👏👏👏👏
Amazing content :)
Really love your content and the energy with which the lectures are delivered. However, you do really seem fascinated with sending data over light :p
However, your content is at a very high level. So for software engineers with not too many years of experience, is it enough, or do we need to go into depth about the working of these protocols?
I believe he is giving us an in depth high level understanding, so we have basic info of how it works and it's existence. We can then go on and search for low level utilizations of it to solidify knowledge.
Very good content .
great content thanks
Awesome)
Bro I have questions plz give answer . Is this video cover RFC 2616 and 7540 ?
Great video!!!
At what point do we choose what version of HTTP we want to use? Can we do it in express.js? Where should we choose the HTTP version
Hey Hussein Nice Explanation, I just have a quick question if the HTTP 1.1 keeps the connection Open how does it differ from web sockets?
Great question, correct both HTTP 1.1 and WebSockets keep the connection open. The difference is WebSockets give you low level access to the socket so you can send/receive information in bidirectional manner.. while HTTP 1.1 only allows for the client to "request" and the server can only respond to a request.. it is a simpler model...
and in HTTP 1.1 when you make a request in the Connection, you will have to wait for a response from the server before sending another request.. this was made better with pipelining but it had its own problems well.. HTTP/2 solved this.
@@hnasr wow thats crystal clear, thanks a lot, also a small clarification you mentioned in your websockets video that websockets uses HTTP, i thought websockts its like a different protocol altogether which runs on top of TCP nothing to do with HTTP?
Hey, isn't there a 3 way handshake during HTTP request? Only a 3 way handshake when there's HTTPS?
Very great video, thank you for sharing this information
Thanks!
9:37 That would be awesome if you create a playlist on status codes (if it does not already exist, I just subscribed yesterday)
Very useful tutorials
Thank you for this ..please make big videos nly they are best
