Which Cache-Control directive allows a response to be stored by any cache?
✗ Incorrect
The 'public' directive means the response can be cached by any cache, including shared caches.

'no-store' tells caches not to store any part of the response.
What header does a browser send to check if a cached resource is still valid?

Browsers send 'If-None-Match' with the ETag value to ask the server if the resource changed.
In Remix, where do you typically set HTTP cache headers?
✗ Incorrect
Remix allows setting cache headers in loaders and actions which handle server responses.
Which header helps browsers identify the version of a resource?
✗ Incorrect
ETag provides a unique identifier for a resource version to help with caching.
