DETECTING AN INACTIVE CLIENT DURING A COMMUNICATION SESSION

摘要

A communication session is established between a first device and a browser on a second device. The communication session is a persistent hypertext transfer protocol (HTTP) session in which a transmission control protocol/internet protocol (TCP/IP) connection persists throughout the persistent HTTP session. A question is transmitted from the first device to the browser on the second device. In response to the first device receiving an illogical response to the question from the second device, the communication session between the first device and the second device is terminated.
