tomcat 4 session timeout

Hello All,

I have a simple JSP which looks like this

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">
<%@ page session="true"% >
<HTML>
<HEAD>
<meta HTTP-EQUIV="refresh" CONTENT="35">
<META http-equiv=Cache-Control content=no-cache>
<META http-equiv=Pragma content=no-cache>
</HEAD>
<BODY>
<%
Object sessionIterator AsObj = null;
int sessionIterator ;
sessionIterator AsObj = session.getValu e("sessionItera tor");
if (sessionIterato rAsObj == null) {
sessionIterator = 0;
} else {
Integer tmpInteger = (Integer) sessionIterator AsObj;
sessionIterator = tmpInteger.intV alue();
}
sessionIterator ++;
out.println("" + new java.util.Date( ) + " ");
out.println("Se ssion = " + session);
out.println("session accessed '" +sessionIterato r+ "' times.");
out.println("Max session idle time in secs = "
+session.getMax InactiveInterva l()+ "");
session.putValu e("sessionItera tor", new Integer(session Iterator)); %>
</BODY> </HTML>

This page accesses the session every time it is invoked. The session timeout
is set to 60 seconds. What I have observed is that, If the page refresh
interval is set to less than 30 seconds, then session lives for a long time,
but if it is longer then session is dropped frequently.

Does this mean, it is not sufficient to access session only once during
timeout period to avoid timeout? I was under the impression that tomcat 4
would restart the 60 seconds timer after every access to session.

Thanks,
Sameer.
