session question for tomcat 4.0.1 and 4.0.2

[Zhiyong Li <Zh...@ibiomatics.com>]

I posted the following message a while ago and have not got any
response. So, I tried it on tomcat 4.0.2 release. However, I got the
same result. I would appreciate your help.

First, of all, the assumption is that you have not turned off session support 
using the JSP page directive, i.e. you do NOT have
<%@ page session="false">
The default is "true", so as long as you do not have this, you are fine.

Now, session.isNew() would continually return "false" if the following 
conditions were true:

1. the browser you are testing with is set to NOT accept cookies,

AND 

2. you are not encoding your URL's in which case Tomcat can not manage 
sessions using URL rewriting, e.g. you should be doing the following in your 
.jsp files :

<a href=<%=response.encodeURL("page1.jsp")%>>Page 1</a>
