Specifies whether the session has been established and the data can be sent and received.
Declaration
Description
This read-only property returns
True if the (secure) session was established, and the server can send data.
If the server can't send the data now,
False is returned.
Check the value of this property before sending information to a client.
However, if the connection is lost
on the socket level, there is no way to find out that the connection has been closed, and Active property can still be True.
The only way to check the actual connection state is to send something and get an error if the connection has been closed.
This is by design of TCP/IP.
Your code should always be ready to handle unexpected disconnections and other network errors and reconnect if needed.
