I am looking for some docs which says how to content is cached

I have a worker deployed, which makes post requests and gets json as response which is cached I think

but I want to know if it's cached in the browser or the local server or is it cached for all workers like kv

which makes post requests and gets json as response

POST requests aren't going to be cached by default.

SSDDOP•1/31/24, 6:27 PM

looks like it's cached

SSDDOP•1/31/24, 6:28 PM

1st response took 2.4 sec then it was ~50ms

dave•1/31/24, 6:29 PM

I can't tell if the your browser is caching or not from that screenshot

dave•1/31/24, 6:29 PM

you can do wrangler tailwrangler tail to see if your worker is being hit or not

SSDDOP•1/31/24, 6:30 PM

there is no implementation for caching

SSDDOP•1/31/24, 6:30 PM

running without remote flag takes around the same time for each req

SSDDOP•1/31/24, 6:30 PM

afaik egress is cached

SSDDOP•1/31/24, 6:30 PM

but at what level

Isaac McFadyen•1/31/24, 6:34 PM

GraphQL requests are cached by default with some GraphQL servers so if it's caching a GraphQL POST then that's probably why.

Isaac McFadyen•1/31/24, 6:34 PM

(as in, not at the CDN level, it would be at the Worker/GraphQL library level)

SSDDOP•1/31/24, 6:35 PM

what's worker level? The local server?

SSSDD what's worker level? The local server?

Isaac McFadyen•1/31/24, 6:35 PM

I assume you have a Worker serving GraphQL requests there?

SSDDOP•1/31/24, 6:36 PM

nope, the back end is our graphql server, it does not have any caching implemented for worker

IIsaac McFadyen I assume you have a Worker serving GraphQL requests there?

SSDDOP•1/31/24, 6:36 PM

yes

SSSDD yes

Isaac McFadyen•1/31/24, 6:36 PM

What GraphQL server is it?

Isaac McFadyen•1/31/24, 6:36 PM

For example, Apollo server sometimes has caching enabled by default.

Isaac McFadyen•1/31/24, 6:37 PM

It's definitely not the CDN caching it unless you have specifically told the CDN to cache it somehow.

SSDDOP•1/31/24, 6:37 PM

we are making some thing like apollo server

Isaac McFadyen•1/31/24, 6:38 PM

It looks like you have a cache of some sort there?

Isaac McFadyen•1/31/24, 6:39 PM

https://github.com/tailcallhq/tailcall/blob/main/src/http/cache.rs

SSDDOP•1/31/24, 6:39 PM

yes that's different thing

SSDDOP•1/31/24, 6:39 PM

it's entity cache

SSDDOP•1/31/24, 6:39 PM

you can use @cache@cache operator in the schema, which caches specific parts of the schema

SSDDOP•1/31/24, 6:39 PM

with specified ttl

SSDDOP•1/31/24, 6:45 PM

I thought you were referring to https://github.com/tailcallhq/tailcall/blob/main/cloudflare/src/cache.rs

but anyways even that code is not used, it was recently introduced, the screenshot is quite old

GaryDix•1/31/24, 11:43 PM

The comments i get are for another worker that is running, the one under fev is silent/

Is it possible to force smart placement to be on?

GaryDix•1/31/24, 11:51 PM

What is that?

GaryDix•2/1/24, 12:01 AM

no one is particualrly talking to anyone

Adi•2/1/24, 2:59 AM

Hey all, question. From the behavior I'm seeing, smart placement does not count requests to R2 as "subrequests", and therefore is not getting past the INSUFFICIENT_SUBREQUESTSINSUFFICIENT_SUBREQUESTS placement status.
Is this expected behavior?

Ddave Is it possible to force smart placement to be on?

Cyb3r-Jak3•2/1/24, 4:02 AM

What do you mean by force? If you set it then it should be on. You can’t force a location though

Sunil Kumar•2/1/24, 6:29 AM

I'm working on a small project i.e.., A user can install there subdomain path form main domain

ex :- hashnode.com //main domain
sunilkumar.hashnode.dev //sub domain like that

we have personal access token to access particular details of a user and later we need to check like what are available domains on the user and we need to take which domain you need to install like that

by using workers how can i achieve this problem .

can anyone help me out the best way to achieve and also some insights and resources

Hi.

So, I have used the default workers example for caching POST request: https://developers.cloudflare.com/workers/examples/cache-post-request

The scenario is the following:

User lands on the page and the POST request to the endpoint is made via XHR (AJAX) call. The Cf-Cache-StatusCf-Cache-Status is DYNAMICDYNAMIC
Same user hits this endpoint with the same payload and CF returns the cached result. The Cf-Cache-StatusCf-Cache-Status is HITHIT
When another user from a different device hits the same endpoint, CF still hits the origin.

How can I serve the same cached response to all users instead of only the one that's requesting the cached URI (endpoint)?

I don't use waitUntil. The thing is I could not reproduce the issue yet when I had logs trailing with wrangler. The only thing I see is that the last API call did not happen. But is there any way to see this in the cloudflare logs to be certain this is actually the issue?

Hello, I’m Allie!•2/1/24, 2:46 PM

Assuming that the logs don't show an error, then I don't think it would be getting cut off. Might be something else being skipped in the code

Hello, I’m Allie!•2/1/24, 2:47 PM

If the request goes through, then it has completed execution, so maybe there are some conditions for an API call that aren't being fulfilled

HHello, I’m Allie!Though, can't you just prevent Cloud Run from booting anywhere other than the US...

dave•2/1/24, 2:48 PM

Cloud Run is booting only in the US. The thing is if the Worker is running outside of the US, the subrequest to Cloud Run is gonna be outside the US for bandwidth billing purposes, no?
