Abstract
A proxy server operative to accept plug-in filters to perform forward and reverse filtering between a client process and a server process. In accordance with one aspect of the invention, a method of filtering information includes the steps of receiving a request by the proxy server from a client. The proxy server identifies a Uniform Resource Locator (URL) of a server process in the request and compares that URL against filter rules previously defined to the system. In the event the URL satisfies one of the filter rules, a filter servlet associated with the satisfied filter rule is used to filter the requested information. A filter servlet is a set of instructions that, when executed, filters the information. The filtered request is then used to retrieve information from a server process. Similarly, the same filtering process may be performed on a response from the server process destined for a client process.
