@Contract(threading=IMMUTABLE) public final class ResponseCacheControl extends Object implements CacheControl
The class provides methods to retrieve the maximum age of the response and the maximum age that applies to shared caches. The values are expressed in seconds, with -1 indicating that the value was not specified in the header.
Instances of this class are immutable, meaning that their values cannot be changed once they are set. To create an instance, use one of the constructors that take the desired values as arguments. Alternatively, use the default constructor to create an instance with both values set to -1, indicating that the header was not present in the response.
