ResponseCacheControl (Apache HttpClient Cache 5.4.1 API)

java.lang.Object
- org.apache.hc.client5.http.cache.ResponseCacheControl

All Implemented Interfaces:

CacheControl
```
@Contract(threading=IMMUTABLE)
public final class ResponseCacheControl
extends Object
implements CacheControl
```
Represents the value of the Cache-Control header in an HTTP response, which indicate whether and for how long the response can be cached by the client and intermediary proxies.
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.
