 A common practice is to use a TCP keep-alive. This practice keeps the connection active for a longer period. For more information, see these [.NET examples](/dotnet/api/system.net.servicepoint.settcpkeepalive). With keep-alive enabled, packets are sent during periods of inactivity on the connection. Keep-alive packets ensure the idle timeout value isn't reached and the connection is maintained for a long period.
 
 The setting works for inbound connections only. To avoid losing the connection, configure the TCP keep-alive with an interval less than the idle timeout setting or increase the idle timeout value. To support these scenarios, support for a configurable idle timeout is available.
