I believe some browsers don't issue a referrer header.
You could always store the page history in the http session. At the top
of every JSP (using an @include or custom tag) you could have code like
this:
<%
String lastPage = session.getAttribute("lastPage");
String currURL;
if (request.getQueryString() == null)
currURL= request.getRequestURI();
else
currURL= request.getRequestURI() + "?" +
request.getQueryString();
session.setAttribute("lastPage", currURL);
%>
You would think there should be an easier way to get the URL, but I
haven't found it.
