 import javax.servlet.http.HttpServletRequest;

 This class is not a "wrapper" per se, but computes the correct path info,
 request URI, etc. for included requests. When including a request via
 javax.servlet.RequestDispatcher, the Servlet API specifies that target paths of
 the included request are available as request attributes.
 Request.getPathInfo(), for example will return the value for the including
 request, *not* for the included one.
