Hello,
This may seem trivial to most of you but I bet this will help learner like
me so heres my question. I use the following method to validate a http
session. I have 2 instance of Tomcat 4.1.24 + mod_jk + Apache2 that
replicate session in-memory (JavaGroups stuff). After I deliberately
shutdown one instance, I see that requests to the other instance but while
validating sessions I go to the line where I put block comments ("I get to
this line on Node 2 ...") and eventually invalidate() them. Why does
session.isNew() return true on the second instance?
private boolean isValidSession(HttpServletRequest request,
HttpServletResponse response)
{
try
{
HttpSession session = request.getSession(true);
if( ! session.isNew() )
{
if( session != null )
{
Hashtable sessionStuff =
(Hashtable)session.getAttribute("someSessionStuff");
try
{
// Do something with "sessionStuff"
...
}
catch(Exception exp)
{
session.removeAttribute("sessionStuff");
session.invalidate();
return false;
}
}
else
{
session.invalidate();
return false;
}
}
else
{
/**************************************
* I get to this line on Node 2 ...
**************************************/
session.invalidate();
return false;
}
}
catch(Exception e)
{
e.printStackTrace();
}
return true;
}
Regards,
Vijay Kandy
