Cache-Control

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:

Value	Description
public/private	This defines whether the cache is public or private. A private cache is dedicated to a single client whereas a public cache is shared by several clients.
no-cache	This defines the cached entry as outdated and enforces the loading of data once again ...
