are flat files served by Tomcat when forwarded?

[Daniel Yawitz]

When Tomcat is integrated w/Apache, what happens when a JSP/servlet forwards a request to a static file (HTML page, image,...)?  Who serves it, Tomcat or Apache?    ex: String newloc = "images/biscuit.jpg"; getServletContext().getRequestDispatcher(newloc).forward(request, response);   thanks, dan
