Cache-Control is a header that helps to deal with the cache. It defines the policy to use for the request/response. Used on a response, it defines how the client should cache the data; on a request, it defines what the server can send back in terms of policy.
This header supports multiple values, which can be concatenated when compatible, separated by a comma. Here are the values you can use to define the way data is cached on the client:
