Methods and apparatus for providing customized security and logging protocols in a servlet environment are described. A servlet engine that includes a security module that assures that only those requests that are properly authenticated and authorized are serviced by a servlet. A logging module provides customized records of both security module and servlet transactions.

Methods and computer systems for providing access to a protected resource are described. In an enterprise computer system, an authentication server provides a client requesting access to the protected resource a credential. In order to access the protected resource, the requesting client presents a protected resource access request in combination with the credential to a server coupled to the protected resource. The server, in turn, requests the authentication server to validate the credential. After the authentication server has validated the credential, the server grants the requesting client access to the protected resource.

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.
