At a client computer, a web browser displays a control for a local utility executed on the client computer, wherein the control includes a link. The web browser receives a user input selecting the control and, in response to the user input, issues a request through the link to a local web server coupled with the local utility. The link includes a domain that resolves to a loopback network address. The loopback network address is a self-referencing address for the local web server at the client computer. The local web server receives the request and provides the local utility with a command portion of the request. In response to receiving the command portion of the request from the local web server, the local utility takes one or more actions based on the command portion of the request.
