Counting and finding real solutions of an equation. Control data (like the phone number) must transit over the network. Possibly 'now' on one host for short-term benefit, to be reverted after the tuning is 'later' put in place on the remote host for long-term benefit. The setsockopt function called with the SO_KEEPALIVE socket option allows an application to enable keep-alive packets for a socket connection. All browser compatibility updates at a glance, Frequently asked questions about MDN Plus. For more information about how to prepare for certificate-based authentication, see the Get an X.509 CA certificate section of Authenticate devices using X.509 CA certificates. The client using IoT SDK sends a keep-alive at the interval defined in the following table: *The C# SDK defines the default value of the MQTT KeepAliveInSeconds property as 300 seconds. @TechnikEmpire: please read the HTTP spec, particularly, Thanks, yes, I understand this. That is what makes the connection "persistent". kept open after sending the response. This is is indeed networking question, but it may be appropriate here after all. IoT Hub translates these attributes into their corresponding system properties. How is white allowed to castle 0-0-0 in this position? This error is returned if the socket descriptor passed in the, Windows2000 Professional [desktop apps only]. Dialog throwing "Unable to add window token null is not for an application with getApplication() as context, TCP loopback connection vs Unix Domain Socket performance. MathJax reference.

It seems so unreal. sockets - Explain http keep-alive mechanism - Stack Overflow * Caution: When decreasing the TCP Keepalive interval, be sure to review the keepalive retry interval and retry count; the latter may need to be increased. For example: The following Python code snippet demonstrates the twin reported properties update process over MQTT using the Paho MQTT client: Upon success of the twin reported properties update process in the previous code snippet, the publication message from IoT Hub has the following topic: $iothub/twin/res/204/?$rid=1&$version=6, where 204 is the status code indicating success, $rid=1 corresponds to the request ID provided by the device in the code, and $version corresponds to the version of reported properties section of device twins after the update.
