TElSSLClient.Enabled property

    This property defines the way TElSSLClient establishes session. When TElSSLClient is enabled, it performs its job i.e. establishes SSL/TLS session and encrypts data. When Enabled is False, TElSSLClient passes thedata unchanged. This lets the application call the same methods regardless on whether the secure or regular session is established.
    Example: when the socket is used for HTTP transfer, the application can use TElSSLClient's method both for HTTPS and plain HTTP sessions by enabling or disabling TElSSLClient accordingly.
    It is possible to change the Enabled state in the middle of the session, thus turning SSL on or off. This is useful when supporting explicit SSL in certain high-level protocols.
