Is it cached?

EErisa Is it cached?

I tried purging the cache, but it doesn't seem to have worked

ErisaOP•7/28/23, 9:58 PM

Both URLs point to the exact same file on my end, which is why I suspected cache

Unsmart•7/28/23, 9:59 PM

it is cache

Unsmart•7/28/23, 10:00 PM

the file has local browser cache and is cached on cf, probably shouldnt do either on a file that can change

valkyrie_pilot•7/28/23, 10:06 PM

Hmmm

valkyrie_pilot•7/28/23, 10:06 PM

Well the file isn't meant to change frequently

valkyrie_pilot•7/28/23, 10:06 PM

And I also purged the cache manually

CClara.The documentation is super unclear. I saw one an example on another page (https:...

If you know the specific URLs, that should work. Though I would recommend using a scoped bearer API Token rather than Global API Key: https://developers.cloudflare.com/fundamentals/api/get-started/create-token/
There are some rate limits specific to it, but yes it would work without upgrading to Enterprise. You can also purge the whole zone at once but I can see why this would be inconvenient if deploys were frequent!

Another potentially more expensive idea would be to have something in the Worker you can quickly reference (maybe a version in a KV value that is updated on build?) and compare to a header in the cache response to know whether that response is part of an old site deployment or not. But this would require reading from KV every request so may not be suitable depending on use-case.

You could also build the version value into the Worker itself if you were redeploying the Worker on each new site deploy for whatever reason

CClara.Would I run into rate limits? It's a static website with whole lot of pages and ...

For free plans it seems to currently be 1,000 URLs/minute, I anticipate that should be fine for a while?

ErisaOP•7/28/23, 10:46 PM

Let me double check if they're documented internally

ErisaOP•7/28/23, 10:47 PM

Okay there isn't any separate paid URLrate limit I can share unfortunately, and yes there is also 1,200 request per 5 minutes but you can submit multiple URls in the same API request

ErisaOP•7/28/23, 10:48 PM

The 1k/minute for free is mentioned here https://developers.cloudflare.com/cache/how-to/purge-cache/purge-by-single-file/
But I don't see anything for other plans

ErisaOP•7/28/23, 10:49 PM

Let me check

ErisaOP•7/28/23, 10:50 PM

30 URLs per call, unfortunately

ErisaOP•7/28/23, 10:51 PM

I do agree that the tags would have worked much better if you were on Enterprise, don't have a lot of recommendations aside from the prior advice about having a version value somewhere which has its own problems

ErisaOP•7/28/23, 10:52 PM

You may be able to get away with updating an env var on the Worker each deploy

ErisaOP•7/28/23, 10:52 PM

No problem, happy to help

ErisaOP•7/28/23, 10:57 PM

I believe it technically requires a redeploy

ErisaOP•7/28/23, 10:57 PM

and then requests will seamlessly move over to the new deploy of the Worker

ErisaOP•7/28/23, 10:58 PM

Like if you update them on the dashboard in the background it redeploys the Worker
