service agent
|
A service agent is an event-driven software program designed to automatically intercept and process in-coming or out-going messages or data exchanges. They are most commonly utilized to abstract and apply common, cross-cutting functions. This alleviates regular services from having to provide these functions.
Service agents are different from utility services in that they do not possess a service contract and are not explicitly invoked. Most vendor runtime platforms provide many service agents; however, they can also be custom developed. Service agents are commonly found in within the message processing logic of a typical Web service architecture.
Service agents are also known as: filters, handlers
