The URL path to the current handler.
This allows a handler to know its location within the URL-space of an
application. Routers should be sure to update this when dispatching to a
nested handler, using the path parameter to change.
handlerPath is always a root-relative URL path; that is, it always
starts with /. It will also end with / whenever url's path is
non-empty, or if requestUri's path ends with /.
handlerPath and url's path combine to create requestedUri's path.
