Class HttpsServerConnection

java.lang.Object

com.prosysopc.ua.stack.utils.AbstractState<CloseableObjectState,ServiceResultException>

com.prosysopc.ua.stack.transport.https.HttpsServerConnection

All Implemented Interfaces:

ServerConnection, IStatefulObject<CloseableObjectState,ServiceResultException>

public class HttpsServerConnection
extends AbstractState<CloseableObjectState,ServiceResultException>
implements ServerConnection

This class implements HTTP TSL/SSL conversation. The messages are serialized using binary scheme, the same as with tcp conversation. Because HTTPS channel is already secure, a OPC secure channel is not opened. All HTTPS communications via a URL shall be treated as a single SecureChannel that is shared by multiple Clients. Stack shall provide a unique identifier for the SecureChannel which allows Applications correlate a request with a SecureChannel.This means that Sessions can only be considered secure if the AuthenticationToken (see Part 4) is long (>20 bytes) and HTTPS encryption is enabled.
