When you use <jsp:include> (or, more generally,
RequestDispatcher.include()), the request parameters seen by the included
page or servlet are those for the *original* request. If you want to see
the parameters related to the include request, this information is
provided in a series of request attributes, as defined by the servlet spec
(see <http://java.sun.com/products/servlet/download.html>).
For example, to grab the "/with/extra/path/info" string above, you would
say:
String pathInfo = (String)
request.getAttribute("javax.servlet.include.path_info");
in the included servlet.
