A number of approaches can be taken to improve the routing of client requests to business protocol destinations. In one such approach, a business servlet registers itself as a default servlet such that it receives any request not recognized by the system. In another embodiment, internal APIs can be used to route all messages to a business servlet, which can use internal APIs to redirect the request if the business servlet does not recognize the request. In another embodiment, filters can be used in conjunction with a lookup table containing address information to route requests to the proper destination.This description is not intended to be a complete description of, or limit the scope of, the invention. Other features, aspects, and objects of the invention can be obtained from a review of the specification, the figures, and the claims.
