Hello,

I am using BlockSocket to connect to some server application - 3rd
party ...

 connection:=TTCPBlockSocket.Create;
 connection.CreateSocket;                    
 connection.Connect(edit2.Text,edit3.Text);

When ever there is a new connection to server, server will send some
"start" data.
In my case if I close the connection with connection.CloseSocket; and
then re-connect with above sequence, server will not send start data,
it looks like it thinks "old" connection was re-established.
How can I clean the "old" connection and reconnect?

For instance if I make more connections to server without closing
connection before, server will always send me "start" data for every
new connection, but this will create to much connections ....

Regards Michox

What OS?
Did you check the status?
How quickly do you reconnect?
Probably a small project showing the problem helps in troubleshooting.
But I would expect the OS to keep the connection for some time before
shutting it down.
