The best, shortest, most succinct illustrated explanation on how to setup nginx web cache proxy. Thank you!

Glad it was helpful! That's what I was going for with this one :)

Thanks. Sometimes I just get tired of having to read through a mountain of man pages to get started. Glad you posted this up

Hello from Costa Rica. This is amazing. You explained so detailed and clear and straigforward. Huge thanks

[@TonyTeachesTech]

You're welcome!

[@tf1n]

Thank you, Tony! I was feeling ambiguity around the process of configuring Nginx for this, but you have reaffirmed how simple it can be from the Nginx documentation. This video helped me make huge gains for a system design project at a programming school. Blessings to you!

bro I love you, thanks for this

[@datajunkie3427]

This tutorial is more than awesome! Thanks bud. What happens if the server at 8000 is dead, will the client still get a copy of the site since it's cached?

[@marcioslsouza]

Hey Tony! Great video explaining how the CDN words on NGINX. I would like to ask you how all this configuration would work in secure mode (SSL) port 443 rather than in port 80?

[@LryuzakiLN]

Caching doesn't seem to work in Django projects, can you make a video on how to achieve it? I don't think you will be able to do it imo.

[@PeterBatah]

Thank you so much for sharing your time and expertise with us Tony. Much appreciated. How would you apply this caching method to Nginx when it is being used as a reverse proxy for multiple sites. Eg. your YT video on multiple Wordpress sites. Have a good one!

[@ramguntha]

Thanks for the informative video. Question(s): 1. Can this cache be used for Json data as well? How do we make sure that nginx does not get confused with the auth tokens that keep changing with every request? 2. When it comes to the static content that is living on the same physical box, how does the caching server make it faster?

[@TonyTeachesTech]

Caching will likely make it faster. Should work on json data too

[@livetvuhddotcom4510]

Hi, your video is so easy to understand. I am new in nginx. I am trying to learn nginx by watching your video. I have an another question. Can you make any video for VOD Streaming Cache server? like, i want to make a cache server for mp4 file. also i want to know about cache file size? if main file size 1 gb then what will be the cache file size? Thanks.

[@IosifHamlatzis]

thnx I was wondering since I have an nginx server (let's name it "haha") already running for HLS & DASH streaming and don't want to mess it up, is there a way to use another server for caching? So someone is watchign a live stream from "haha" can I have this stream also cached?

Hi Tony... video is very informative and covers basic caching. I have a query, while setting up the cache, you made the configuration to cache anything. So if I want to cache a specific image or web page, in that case how would I configure. Thanks in advance.

Sorry, I don't have this information

[@NoCommunists]

Thanks for your tutorial, but I want to cache video for faster serving on my server, is it possible without using CDN ? (because it's kinda expensive) Is there any way to cache video like ready for serving for any visitor visit a video URL (.mp4 URL) that been already cached on server ?

[@motidana4883]

very productive. thankyou for such great content. I have a small question. If I am looking to serve static content (js,css, png, gif, etc) and couple of REST API dynamic PHP calls as well, and say i have to serve these static assets at the same time to 20,000 concurrent users, will this approach to add cache server in front of a origin nginx server, will that be helpful, if so to what extent?

[@TonyTeachesTech]

This type of cache is only helpful for caching dynamic content that doesn't change too often. I don't see it helping much for static content

[@motidana4883]

​@@TonyTeachesTech thanks for your reply so do you see any good technique to optimize static content delivery from with in Nginx or CDN is only way to go?

[@engchoontan8483]

The transparent-proxy and cache probably cannot work for "win11 file-manager" due to the sabotaged browers and other- OS.sss with advertising being number-1 and everything else (games) will only load after forced-advertising(duration, times) thus making advertising the owner of devices. If the video is down due to advertising-servers being cut-off due to internet tier-one exchanges in disagreement due to war or just women-meeting micro-managing... just boot into linux and use the browser for something else like internet-TV

[@engchoontan8483]

China learnt to hack using the advertising due to the size-of payload possible and the bypass of security and the ... of permissions and the control of hardware and ... older-OS.sss should be in the bootloader-chainloader(list-sequence of defaults)

i wish you would explain all the caching parameters you wrote more clearly , thanks

[@TonyTeachesTech]

Sorry for that

[@JustinAvery]

Amazing, but none of my cache files are getting written and therefore I'm getting no cache hits. Any idea why? This is using a nginx proxy with proxy_pass, and using proxy_ssl_session_reuse (these are the only differences I can see)

[@TonyTeachesTech]

Hmm I'm not sure why that's happening for you

[@amalms6573]

Hi Tony... Why do we need to change the website listening port? Can we do this without changing the website port?

[@TonyTeachesTech]

This is so the cache can communicate with the frontend. You can pick any ports you'd like

Hi Tony, nginx is serving old files instead of new updated files of my angular application. New features aren't visible. I checked in Network tab of chrome console. It shows old files instead of new files. Can you suggest a solution? I'm tired of finding solution and can't figure out what to do.

[@TonyTeachesTech]

I'm not sure why that's happening to you, sorry

[@chrisivonne3739]

Does this work for Bitnami NGINX? The var/cache/nginx folder doesn't get auto-created and manually doing so causes the directory to be unwritable resulting in the response header to be missing caching instructions.

[@TonyTeachesTech]

Hopefully Nick will be able to help you out :)

will it work in cloudflare dns? or localhost only? thank you Tony.

This method is not working with wordpress, like when I add a new post old cache should be deleted also in update. Could you please make a video on proper caching for WordPress in NGINX?

[@TonyTeachesTech]

Oh yes, we'd have to do a bit more than this basic example. I can look into this for a future video.

[@C00ltronix]

With Wordpress you can user Redis or fastCGI at server level and then have a plugin to delete cache when needed. Or get a easy server stack such as Wordops, Centminmod etc. that makes it easy to setup and change stuff.

[@armanism24]

@@C00ltronix Ofcourse I used this method earlier but I want to do it manually.
