The proxy settings for a browser are modified to route public Internet traffic through a local client assistant, while keeping previous proxy policies intact. The process compares the previous proxy results for a known, public Internet address to the previous proxy results for the desired Internet address. If the two proxy results are equivalent, then the request is directed to the local client assistant, otherwise the request is directed according to the previous proxy results. If the testing of the public Internet address had resulted in the use of a proxy, then the local client assistant will route its requests to the proxy so indicated.
