Which HTTP headers are responsible for caching?

The main HTTP headers responsible for caching include:

• Cache-Control: sets caching rules, e.g., max-age, no-cache, no-store, public, private.
• Expires: indicates the date and time after which the resource is considered stale.
• ETag: a unique identifier for the version of the resource, used for conditional requests.
• Last-Modified: date of the last modification of the resource, helps determine if the resource has changed since the last request.

Example of using Cache-Control:

Cache-Control: max-age=3600, public

means that the resource can be cached publicly and considered fresh for 3600 seconds.
