You can use request.getRequestURI() to get the complete URI used to invoke the
parent page, since no URI path information is changed when you include a page.
If you want the context/application-relative URI, use request.getServletPath()
instead. Context relative paths (i.e. the URI path minus the context's URI
prefix) must be used in <jsp:forward> and <jsp:include>, while a complete URI is
needed when you call sendRedirect().
If you use forward instead of include, the URI path information *is* changed
to that of the target JSP/servlet. You can still get the URI path info that
refers to the parent through a number of request attributes in the target JSP:
javax.servlet.include.request_uri
javax.servlet.include.context_path
javax.servlet.include.servlet_path
javax.servlet.include.path_info
javax.servlet.include.query_string
All of this, and a lot more, is described in the Servlet 2.2 specification
available at <http://java.sun.com/products/servlet/index.html>. Do yourself
a favor and save a lot of time by reading both the JSP and the Servlet specs.
They actually tell you how things are supposed to work ;-)
