Any debian/ubuntu box should have ufwufw installed IMHO

David WangOP•10/23/24, 10:51 PM

Eh. Unnecessary overhead to me

fry69•10/23/24, 10:53 PM

Well Cloudflare is also "unnecessary", but makes life so much easier.

People would disagree with the WAF rules and ddos protection

Unnecessary overhead when you just want raw performance, like writing your own iptables scripts

David WangOP•10/23/24, 10:57 PM

Um. No. Cf handling the firewall and ddos protection takes the overhead off the server

David WangOP•10/23/24, 10:57 PM

As long as you have an origin server which serves stuff you need to administrate that, e.g. with tools that are available there. I can only recommend to a have a look at ufwufw, it is pretty simple and very useful for these tasks. Also helps avoiding yourself shooting in the foot, aka locking yourself out by accident.

David WangOP•10/23/24, 11:01 PM

So far my foot is free of bullet holes

David WangOP•10/23/24, 11:01 PM

I've heard of ufw but i don't see the need for it

DDavid Wang Although i heard proxying adds time to the request cycle. Is that right?

fry69•10/23/24, 11:02 PM

Of course a proxy adds latency and processing time when the request needs to get forwarded to the origin server, but if static content can get cached by the proxy, it reduces this overhead, so it should be in almost all cases advantageous.

David WangOP•10/23/24, 11:02 PM

Having CF proxy on doesn't automatically mean caching is on, does it?

DDavid Wang Having CF proxy on doesn't automatically mean caching is on, does it?

fry69•10/23/24, 11:04 PM

If your origin server sends content with correct cache flags, I'd be surprised if the CF proxy would not cache those

fry69•10/23/24, 11:05 PM

You can turn the cache off in a "development mode"

fry69•10/23/24, 11:08 PM

Looks like 4h cache time is default for a standard proxy setup

David WangOP•10/23/24, 11:10 PM

Hm. Ok

David WangOP•10/23/24, 11:10 PM

I'll have to look into that

RyanKnack•10/23/24, 11:58 PM

This is a full documentation of CF's default caching behavior.

This is useful cuz if you need specialized caching behavior, this can tell you where to look and what to cache if you need it in your use case

https://developers.cloudflare.com/cache/concepts/default-cache-behavior/

Cloudflare Docs

Default cache behavior | Cloudflare Cache (CDN) docs

Cloudflare respects the origin web server’s cache headers in the following order unless an Edge Cache TTL cache rule overrides the headers. Refer to the Edge TTL section for details on default TTL behavior.

Hi everyone, first time looking into this flow. Let's imagine that a website has an option to upload an image. Let's say that image goes into Cloudflare R2 or some other cloud storage.

Is there a way to automatically trigger some event to transform this original image into multiple ones, with different sizes? Let's say 100x100, 200x200, etc? Without a proper backend running, but allowing us to pre-processing it?

I was thinking in something like a Cloudflare worker as a service, which triggers somehow on a new image upload and generate new ones, with some lib and finally uploading them into R2 again.

Am I in a fog or is this something doable and okayish? I'd need a free plan to test this, so alternatives like Cloudflare Images aren't really an option right now, afaik. Thank you

TL;DR: transform original image into multiple ones with different sizes. Save on Cloudflare R2. Pre-processing (not at each request)

valkyrie_pilot•10/24/24, 5:58 PM

i think the biggest problem is doing it on upload

valkyrie_pilot•10/24/24, 5:58 PM

if you can upload through a server this is super easy

Nelson Sousa•10/24/24, 5:58 PM

But then the server is the one responsible for getting the image and pre-processing it, in the same sync flow, right?

Hello beautiful people.
I am looking to sign up for the pro account that includes WAF.

One question though - am I understanding the documentation correctly that custom TLS are supported and I only need the Business Account if I want to buy certificates from CloudFlare directly ?

NNelson Sousa What kind of queue do you recommend?

WTDawson9•10/24/24, 8:18 PM

It depends on what you would use as a backend

Nelson Sousa•10/24/24, 8:18 PM

Whatever is best

main stack is C# but working now with TS

WTDawson9•10/24/24, 8:19 PM

For me personally, I would:

- Receive the image from the user or whatever the API route is
- Save it and tag it (Give it an ID and save information about it for later on)
- Add it to the end of some kind of queue file
- Every so often, go to the first image on the queue, take it off the queue, process it and then send it to Cloudflare R2

But not universal, which is my point. I don't think any of my VPSs have it installed
