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.

1. A proxy host computer comprising:

a configuration database of services associated with browsers, further comprising a plurality of configuration pages representing different sets of services; and

a database updater to update services associated with a browser upon receipt from the browser of a request for a configuration update, said request selecting one configuration page from said plurality of configuration pages.

2. The proxy host computer of claim 1, wherein the configuration database includes associations between services and attachment points of browsers.

3. The proxy host computer of claim 1 further comprising a wireless radio link connecting the proxy host computer to the browser.

4. A method of accessing and retrieving information in a networked data communications system comprising, at a proxy:

receiving from a browser a query directed to an information source;

establishing a set of services associated with the browser;

selecting a method of filtering to apply to the query as a function of the set of services associated with the browser;

modifying the query according to the method of filtering to provide a modified query;

forwarding the modified query to another information source;

receiving from the another information source a response to the modified query; and

forwarding the response to the browser.

5. The method of claim 4 further comprising:

at the browser configuring the browser to direct the query to a specific attachment point of a plurality of attachment points of the proxy; and

wherein said step of receiving further includes receiving the query at the specific attachment point and said step of establishing a set of services depends on the specific attachment point.

6. The method of claim 4 wherein, the step of modifying the query
