Application files should not be served from action.parabol.co

[Dschoordsch]

All files in the parabol-static cache are served from the webserver directly instead of the CDN.

The 300 files amount to around 1.6 MB

this is so weird because those URLs are invalid. if you look at the preview you'll see each one returns our HTML, not even the assets 🤔 . tbh not even sure how the app is working in its current state

[Dschoordsch]

Looking at the static and dynamic cache we have:
static: /TeamFilterMenu_d462eccfa23818e42d74.js
dynamic: /production/build/TeamFilterMenu_d462eccfa23818e42d74.js
So we're just fetching everything into the dynamic cache, the static one seems to be fully ignored

Ignored but downloaded at least once, isn't it? 🤔 I mean, that can still be a problem on releases with a lot of clients connecting at the same time. We should fix it anyway, or get rid or the static cache if that make sense

I must've goofed this up when writing the service worker URLs.
As @rafaelromcar-parabol suggested, even though it's just returning a bunch of 404s, it's doing so against our webserver, so whenever a new version gets released each connected user is reconnecting & issuing like 300 requests to our webserver, which is a whole bunch of traffic all at once!
