Better to change my question:
When a session associated with a client is created?
Hi,
I have a filter (for /*) in which I'm caching something in the
session. Here is a piece of code:
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) {
HttpServletRequest req = (HttpServletRequest) request;
HttpSession session = req.getSession(false);
if (session == null) {
System.out.println("Create a new session: " + new
java.util.Date());
session = req.getSession();
}
// cache something
}
The first time I make a request, since req.getSession(false) returns
null, a session is created by a call to req.getSession() manually.
The second time I make a request to the server, req.getSession(false)
returns null and so a session is created again.
In all other request (third, ...) the last created session (second) is returned!
My question is why session is created two times?
Thanks in advance.
