25  * Test to ensure that a forwarded-to servlet can receive request attributes
26  * set by the calling servlet, as well as set their own request attributes.

28  * The test forwards to either a servlet ("/Forward03a") or a JSP page
29  * ("/Forward03b.jsp") depending on the value specified for the "path"
30  * parameter. The default is the servlet.
