Getting referrer in error page setup in web.xml

Question

          Hello,
          Is it possible to get the referrer in a JSP when that JSP is
          set up as the error-page element in web.xml when a 404 (or
          any other http error) occurs?
          For example when I type www.me.com/page1.jsp and page1.jsp does
          not exist WLS sends me to my error page. However I want to know
          what page (in this case page1.jsp) it was trying to access.
          Wouldn't this typically be the referrer? When I itirate through
          the headers in my error page the referrer is not one of them.
          regards,
