HTTP: What is a private cache?

In a nutshell

A private cache is associated with a specific client (e.g., a browser cache). The stored response is not shared with other clients so a private cache can store a personalised response for a specific user.

You can tell browsers that a response contains personalised content by specifying the private directive:

Cache-Control: private
