Closes #7546
Set
Cache-Control: max-age=0, must-revalidate
. AFAICT, this effectively means "never reuse cached assets".For files in the dist dir, we already send a
last-modified
header for assets, so send 304s in case they haven't changed.For all other endpoints, it will just send the full response (and behave like
no-store
).Not sure if we want to add tests for this...
Webpack (or at least create-react-app) does the same thing, but based on etags instead of mtime.
