SecureCacheResponse getSSLSession() in Java

getSSLSession(): This method is available in the java.net.SecureCacheResponse class of Java.

Syntax:

Optional<SSLSession> java.net.SecureCacheResponse.getSSLSession()

This method returns an Optional containing the SSLSession in use on the original connection that retrieved the network resource.

Returns an empty Optional if the underlying implementation does not support this method.

Parameters: NA

Returns: an Optional containing the SSLSession in use on the original connection.

Exceptions: NA

                List<String> value1 = new ArrayList<String>();
                value.add("abcdsdd");
                map.put("Authorization", value);
                value1.add("abcdd");
                map.put("param", value1);
                return map;
            }

            @Override

                return new InputStream() {

                    @Override
                    public int read() throws IOException {
                        return 0;

        };

        System.out.println(secureCacheResponse.getSSLSession());

    }
}

Output:

Optional.empty

Some other methods of the SecureCacheResponse class

getCipherSuite(): This method returns the cipher suite in use on the original connection that retrieved the network resource.

getLocalCertificateChain(): This method returns the certificate chain that was sent to the server during the handshaking of the original connection that retrieved the network resource.

getLocalPrincipal(): This method returns the principal that was sent to the server during handshaking in the original connection that retrieved the network resource.

getPeerPrincipal(): This method returns 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 returns 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.

getSSLSession(): This method returns an Optional containing the SSLSession in use on the original connection that retrieved the network resource.
