In proxy caching, what does NGINX cache?

Responses from upstream servers

An NGINX reverse proxy caches responses from an upstream server. The upstream sends an ETag header. What does NGINX do when a cached response expires and a client requests the same resource?

It ignores the ETag and always fetches a fresh copy from the upstream.

It sends a conditional request to the upstream with the If-None-Match header containing the ETag.

It serves the stale response without contacting the upstream.

It deletes the cache entry and forwards the request to the upstream.

An NGINX reverse proxy caches responses from an upstream API. The API returns different data based on the Authorization header. The team wants to cache responses per user, but they are concerned about security. What is the best approach?

Cache all responses without considering the Authorization header.

Include the Authorization header in the cache key and enable proxy_cache_valid.

Use proxy_cache_lock to serialize requests per user.

Disable caching for requests with an Authorization header.
