Override options for a cache strategy.

maxAge number: The maximum amount of time in seconds that a resource will be considered fresh. See max-age in the MDN docs.
mode string: The caching mode, generally public, private, or no-store.
sMaxAge number: Similar to maxAge but specific to shared caches. See s-maxage in the MDN docs.
staleIfError number: Indicate that the cache should serve the stale response if an error occurs while revalidating the cache. See stale-if-error in the MDN docs.
staleWhileRevalidate number: Indicate that the cache should serve the stale response in the background while revalidating the cache. See stale-while-revalidate in the MDN docs.
