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.

[@MichaelThomasDev]

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

[@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.

[@munishthakur8018]

Such a detailed yet concise video. Loved it !

[@muthualagappan4348]

Single video explains everything about HTTP caching! Highly Informative.

[@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

[@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!!!!

Great video, thanks.

[@OutOfTime42]

Amazing content!

[@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

[@modex98]

thank you sir for this really helpful video

best video on http caching

[@TerenceKearns]

Excellent.

[@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.

[@sabuein]

Thank you.

Sir very interested lectures

[@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.

[@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?

[@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 :)

[@gsmfunnyandshortfilmsvideo6491]

tq sir

[@geethareddy9936]

nice videos

[@danisimeonov4759]

Great video! What did you use to make animated graphics in the beginning? Have some use cases I would LOVE to demonstrate like this for training purposes. Thanks!

[@roadmapsh]

Thanks, it's Keynote

[@VideoNash]

thanks

[@geethareddy9936]

nice

[@kylemattimore]

Thank you for the video - A small correction, I think "s-max-age" is actually spelled "s-maxage"?

[@roadmapsh]

Ah yes, there is a typo. It's s-maxage. Thank you for pointing out.

[@yingzhoujiang2842]

I am so interested with this font! May I ask what is this font in your videos?

[@roadmapsh]

Hey, it's Kalam

[@rossli8621]

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

[@rinkishahi6289]

Can you please explain about surrogate-control headers also..

[@mithilinamdar2443]

Can you tell how to change softal instrunt in Serum, please ?!
