public abstract class WebContext extends ContextBase
Extended Context that provides web based applications that use it a "generic" view of HTTP related requests and responses, without tying the application to a particular underlying Java API (such as servlets). It is expected that a concrete subclass of WebContext for each API (such as org.apache.commons.chain.web.jakarta.servlet.ServletWebContext) will support adapting that particular API's implementation of request and response objects into this generic framework.

The characteristics of a web request/response are made visible via a series of JavaBeans properties (and mapped to read-only attributes of the same name, as supported by ContextBase.
