Try to cache static resources.
Static non media file's timestamps are hashed at compile tome so that modifying them invalidate old cache.
~~For some reason, plume-front.wasm isn't loaded from cache, even if it contains the right headers.~~
I changed nothing and now it is? I guess I'm ok with it
~~I'll look into adding Etag support too~~
All response made from templates and not containing a form are now Etag-cached

i'd rather this wasn't random, but deterministic

such as the file's she256sum

What is your issue with it being random? It's fixed at compile time, so assuming a production server, which may restart but won't recompile often, the cache will be ok. My first through was using git commit sha, but this may be unnecessary information disclosure

if nothing about the code changes, the cache_id shouldn't change either

The build won't be run again if the code didn't changed, so the ID will not change.

You should probably remove it from Cargo.toml too.

yes, in our development environment that is true, but not for anyone building packages or container images of our software. they always start from a clean slate

I think there are plenty, but I'm lazy and it's a build script. I prototyped using bash, so my rust code is basically bash translated (if you find it really bad, I can change that but I don't know if it's really useful)

Probably obvious, but why do we disable caching on pages with a form?

If the page contain a form, the csrf token will be cached, and may no longer match user's cookies. As these tokens are added later by a fairing, there is no way to detect the page changed here. The other solution could be to allow caching of page and for rocket_csrf to remove ETag when appropriate
