I have just learned more in 8 minutes than 3 years of studying Systems in high schools

[@veeruchowdary9076]

yes bro😆😆

[@edwingarcia5043]

That's sad

[@sukulmahadik0303]

Very Good video . Loved the Coin flip Analogy for Stateless. My Takeaways : 1) HTTP is stateless. Sessions and Cookies make HTTP stateful. 2) HTTP Actions : GET, POST , DELETE 3) HTTP provides status codes --> 200 - OK. 404- not Found 4) HTTP headers allow us to add additional info with our requests. Headers can be predefined , but we can use our own

Dang. Good stuff man. Thanks for sharing your knowledge.

[@mr_o47]

I don't know how I came accross this channel but slowly im falling in love with your content its great and informative

[@imCalezu]

Thank you so much for these videos! Could you possibly cover some specific technical interview questions such as string manipulations, arrays, stacks, linked lists, etc?

[@crystalkewe]

This is such a great video explaining the core concepts/characteristics of HTTP. Thanks Dave!

[@Laurens_Monstrosity]

Clear, Simple & straight to the point. Loved it

you are f'ing good! clears up a lot of uncertainty for the middle-aged guy

[@dikshabhatia6052]

Great video. Loved the way you explain the concept in easy pointers.

[@joshuacushing2858]

Really clear. Thank you. You will likely be a go-to in my path to software engineering.

thank you. u made it simple to understand, i was struggling

Thank you for this public service, Dave!

[@khaledMohammedRagheb]

it is very useful i suggest to use wireshark to show example of the HTTP content I suppose it will be more clear but it is very good video anyway

Really nice! Pretty systematic and easy to grab. New thing learned cache-control response header. Great :)

[@jnaras]

Great simple explanation. Great work.

[@moresnackspls]

Nice video. Btw- 400 level error = problem with sent request (aka 404 requested file doesn't exist) 500 level error = internal problem on server (something went wrong in server scripts)

[@furqans.mahmoud4511]

Wow, Very easy to catch up with this informative video, Thanks alot

[@swapnilp1764]

Great video Dave... Thank you. Could you please create a video on REST & SOAP Thanks.

[@imnormal9263]

Great one Dave, but can you also explain how HTTP is used to exchange information between client side and server side, and the use of HTTP daemon and filtering. Thanks and look forwards to more videos...

gooooood video,thanks.

[@minhoking]

Yo Dave, just wondering if you could do a video on CMU student life. I just saw your video on your CMU, which was great, but it focused primarily on academics. As a senior, considering ED to CMU, it'd be great to hear from a local, eg. public transport, weather, nightlife, stuff to do, eat etc. Cheers x

[@DaveXiang]

That's a good idea, Thanks!

[@mohanj3018]

great stuff :)

[@AlejandroThacker]

Great!

[@puneethrao3659]

amazing video.thank you :)

[@mikewoitt8111]

very helpful as I learn about a computer

[@Elcientifiko]

Hi Dave, on minute 0:20 did you mean that HTTP is the backbone of the web? Because the internet is so much more than that and there are many other protocols that are not worth mentioning here as their implementation on the web isn't as crucial as the HTTP but still relevant in other section of the internet that we can't normally access through a web browser. BTW your videos are very informative. Thumbs up!

[@DaveXiang]

yes, that is a slightly misleading phrase. it's a big part of the Internet! I probably should not have said backbone. You are right, there are many other technologies being used!

[@tubeMonger]

It’s the backbone.

[@chandrasekharreddy7266]

Wow!you are so nice because of you I got 100 marks in my test

Hello Sir, Your videos are really amazing, you are making it easy for us to understand difficult topics ... I've a request just make a video on "Quantum computers" as it is not that easy to understand for everyone ... Thanks & keep continue this great work (Y)

Hello Dave, what I still don't understand is what hyper text is, in other words what is hyper text, but the explanation was Good though,all the other points I understood them,thank you so much for the video

[@lalienamande7137]

What are the functions and include the word text to hhtp?

[@fatharaniwafda4463]

so what is different between HTTP and FTP?

[@jasonreviews]

we developers call it a get Request on the ajax. in node it's called request.

[@lonwabomnyaiza2654]

Dude do you have a whiteboard in your apartment?

[@DaveXiang]

Yea, I do. It's not very big though. I've tried to make a video with it once and I just couldn't pull it off well.

[@technicalvoice225]

Very helpful video. You said http uses TCP/iP in 99.9 percent. Is there any case where it does not use TCP?

yes, i also have same doubt.!
