The SecureCacheResponse Class in Java represents a cache response originally retrieved through secure means.
Syntax: Class Declaration
public abstract class SecureCacheResponse extends CacheResponse
The constructor for this class is as follows
SecureCacheResponse()
Now, the methods of this class are as follows:
| Method | Description |
|---|---|
| getCipherSuite() | This method is used to return the cipher suite in use on the original connection that retrieved the network resource. |
| getLocalCertificateChain() | This method is used to return the certificate chain that was sent to the server during handshaking of the original connection that retrieved the network resource. |
| getLocalPrincipal() | This method is used to return the principal that was sent to the server during handshaking in the original connection that retrieved the network resource. |
| getPeerPrincipal() | This method is used to return the server’s principal which was established as part of defining the session during the original connection that retrieved the network resource. |
| getServerCertificateChain() | This method is used to return the server’s certificate chain, which was established as part of defining the session in the original connection that retrieved the network resource, from the cache. |
