Abstract

A client computer includes a web browser connected to a local web server that is coupled with a local utility. Upon loading a web page, the web browser sends, to the local web server, a first open-ended message that does not require a return message from the local web server. In response to and upon receiving a response to the first open-ended message, the web browser maintains communication with the local web server by sending a second open-ended message that does not require a return message to the local web server. The local web server receives the first open-ended message, waits until the local utility determines that there is information to be provided to the web browser, and in response to determining that there is information to be provided to the web browser, sends a first return message including the information to the web browser.
