Abstract
A query (160) is sent from a browser (100, 101) to a proxy (300) directed to an information source (140) in a networked data communications system. In one aspect, the query is modified by the proxy to provide a modified query and the modified query is forwarded to the information source (120). A response (170) is received at the proxy from the information source and forwarded to the browser. In another aspect the response is modified by the proxy to provide a modified response (370) which is forwarded to the browser. The proxy (300) has a proxy configuration database (340) including a file (341) of services identifying a method of filtering for a specified browser (100) and filters (302, 304) for filtering responsive to the file of services, respectively, queries from and responses to the specified browser. The method of filtering may vary or be modified, for example, according to attributes of the URL within the query, proxy attachment point (310) for the browser, response content, or changing browser requirements, as user, device, or network service needs change.
