Users might already have the file cached. If website-a.com links to [link] , and a user goes from there to website-b.com who also links to [link] , then the user will already have that file in their cache. Penalty: Caching. This makes it very safe and sensible to enforce a reasonably aggressive cache policy.

Because microprocessors are so fast, computer architecture design has evolved towards adding various levels of caching between compute units and the main memory, in order to hide the latency of bringing the bits to the brains. This avoids thrashing caches too much for B and evens out the pressure on the L3 caches of the machine.

If you wanted to cache a file ‘forever’, you’d probably use a Cache-Control header like this: Cache-Control: max-age=31536000 This instructs any cache that it may store and reuse a response for one year (60 seconds × 60 minutes × 24 hours × 365 days = 31,536,000 seconds ).
