The Cache-Control general header field is used to specify directives that MUST be obeyed by all caching mechanisms along the request/response chain.
Cache directives must be passed through by a proxy or gateway application, regardless of their significance to that application, since the directives may be applicable to all recipients along the request/response chain. It is not possible to specify a cache- directive for a specific cache.
