Plug.CacheControl

There are two methods of overwriting the default header value - static and dynamic. The static method can be used by providing a default option to the plug as shown below. The option's value must be a list of clauses and values if there're not boolean clauses.

plug Plug.CacheControl, default: [:public, max_age: {1, :day}]

The dynamic method of setting a value to the cache-control header can be used by providing a dynamic option to the plug as demonstrated below. The option's value must be a unary function, taking a Plug.Conn as an argument and returning a list of clauses.

plug Plug.CacheControl, dynamic: &SomeMod.get_dynamic_clauses/1
