Hope someone can help:
Config: Win NT, Tomcat 3.2.3, Apache 1.3.2 ( according to bundled changes
log).
Have configured a simple JSP app that starts at a login page and maintains a
session bean across pages.
At the start of each page we need to check for no session/session expired.
If this is the case then response.sendRedirect() is used to redirect to a
page that explains this:-
----------------------- Start of *.jsp -------------------------------------
<%@ page language="java" %>
<%
HttpSession oldSession = request.getSession(false);
if( oldSession == null ) {
response.sendRedirect( response.encodeRedirectURL(
"../jsp/no_session.jsp" ) );
}
%>
--------------------- Rest of *.jsp would follow here
---------------------------
This just does not work as we would like. When a redirect happens the
generated html page, no_session.jsp, gets filled with rubbish. It is as if
there is a buffer that is not being flushed somewhere.
I have noticed in the 'rubbish' that gets displayed the odd exception
(invalid state on one occasion), but this is not consistent and more often
displays fragments of HTML from the target page.
Advice welcomed.
Cheers, Mark.
