Abstract:
1. A method comprising: establishing, by a first device, a communication session between the first device and a browser on a second device, wherein the communication session initially remains open on a first device-side, via a TCP/IP connection with the second device, even after the browser on the second device is subsequently closed, and wherein the communication session is a persistent HTTP session in which the TCP/IP connection persists throughout the persistent HTTP session; transmitting a message from the first device to the browser on the second device, wherein the message is a question; in response to the browser on the second device failing to actively respond to the message from the first device, terminating, by the first device, the communication session between the first device and the browser on the second device; and in response to the first device receiving an invalid response to the message, generating an error message in the server that causes said terminating of the communication session between the first device and the second device, wherein the invalid response is an illogical response to the question.
