I'm using portal v2.4.
Problem;
The portal is configured to use security.
The user has to logon to the portal when accessing a pate.
I have a portlet that start's up a new window using javascript.
Within this window I'm communicating directly with a servlet/jsp page.
The timeout of the portal is set to 5 minutes.
Every 3 minutes the new created window is refreshing the page using the session id of the main portal.
After 5 minutes the portal is flushing the session because it thinks that it isn't used anymore.
On the next refresh of the window a http status message 403 - Access to the requested resource has been denied is shown, because of the flush of the session done by the portal.
How can I make sure that the portal and the webserver are using the same refresh on the session?
