Abstract

At a client computer, a web browser is connected to a local web server. The local web server is coupled with a local utility executing on the client computer that is distinct from the web browser. The web browser sends, to the local web server via a first communications channel, a first open-ended message that does not require a return message. The local web server waits until the local utility determines there is information to be provided to the web browser and sends, via the first communications channel, a first return message responsive to the first open-ended message. The web browser, in response to and upon receiving the first return message responsive, maintains communication with the local web server by sending, using a second communications channel distinct from the first communications channel, a second open-ended message that does not require a return message to the local web server.
