Specifies whether secure session is established before sending the data.
This property defines the way
TElSimpleSSLClient establishes the session.
When TElSimpleSSLClient is enabled, it performs it's job i.e. establishes SSL/TLS session
and encrypts data. When Enabled is False, TElSimpleSSLClient passes the data 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 TElSimpleSSLClient's method both for HTTPS and plain HTTP sessions by enabling or disabling TElSimpleSSLClient 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.
Default value is True.
