Everything you need to know about HTTP Caching

Web Cache or HTTP Cache allows you to store a copy of a resource and serve it back when requested. Serving the item from the cache, instead of re-downloading it from the origin server eases the load on the server, improves performance, and reduces the bandwidth usage on the server. In this lesson, we look at the different types of caches, we look at the different HTTP cache headers such as expires, pragma, and cache-control. Also, we understand how the cache validation works and what are the different caching strategies.

I typically watch videos at x2, but this video was so jam-packed with useful information that my brain had no chance to keep up. Thank you so much for arranging this!

[@markwitmer5498]

Exactly.

[@worldOFfans]

true

[@jottaz144]

I normally never comment but this is a great video. Your style is authentic, your slow-paced explanation, accent and articulation are impeccable and I could really grasp everything I needed.

[@frustratedalien666]

I spent hours reading through the RFEs and you condensed that into a video that's 13:32 long lol. I don't think I have ever come across such a short but informative video before.

[@MichaelThomasDev]

This is THE best video at explaining the HTTP response header!

[@isaacneace168]

This video is so helpful. There doesn't seem to be many resources on the internet surrounding this topic, so it was really nice to have a video to break it down

[@munishthakur8018]

Such a detailed yet concise video. Loved it !

[@sourabh.m476]

This is simply superb.... i literally would have had to browse some 1000 videos to find each topic separately and even that might have not helped me. This video is a complete wonder...i now know the l basics of HTTP strongly and feel confident. Thank you!!!!

This video format is very similar to RFCs format, nice.

[@anshikagupta4931]

Great content , thanks !

[@jimknoll]

1st thanks I think this was a complex topic and you provide a clear treatment. I often struggle when I’m addition to all these places there is also a CDN. For example cloudfront from AWS. And there are static files on S3 but lambda at edge may be also involved. It is as if the internet gods want to keep clear answers out of our reach. I have suggested others watch you video as it is. Would do that for any subsequent video covering how cdn interact with this topic

[@heliocloud3767]

Really thanks. That min 1:04 image is what a just needed to understand it.

best video on http caching

[@teomandi]

Great video. I would like to ask although, what should be the preferred caching strategy for an application that uses bearer authetication and uses have different authentication scopes for users?

[@ansarm1785]

Thanks Man 😍😍

[@srinivasasowmiyan2272]

Thanks a lot💌

[@yqy7527]

Thank you!

[@SathishKumar-lt9cg]

Hi, very much helpful, thank you
In cache-control header s-max-age=3600 (content can be cached at public places) alone is used, it also caches at the client-side.

[@jottaz144]

Yeah, I guess it would have to revalidate everywhere every 3600 seconds. By everywhere I mean client browser, CDN, proxys, etc.

[@poojavashishta6207]

very informative

[@kousarazhar_]

Thanks!❤🤓

[@TerenceKearns]

great!!!

[@mohammadjaouni]

great bro

[@madgadget4633]

A few minutes in and I can already deduce it will be an eloquently detailed video about an abstract topic presented in a manner that's understandable for anyone. Straight to the point content with no overproduction or pointless long intros is so refreshing to see.

[@naoufalhamdache8968]

Hello, thank you a lot for your explanations, your videos, graphics and articles are amazing. I don't know if it's wanted, but you have added a video in the React App Playlist that is not related to the subject :)

[@roadmapsh]

Ah, Thanks Naoufal. I have removed it, not sure how it got there :)

[@arshadmehmood4754]

Sir very interested lectures

[@manpreetsrmcem]

what is difference in caching and state Management in angular ?

[@rossli8621]

Is there a typo at 03:45 where the "content-control" should be "cache-control"?
