Hi,
I'm experimenting with multiple instances using round robin. All is
fine except that I'm seeing the session restoration error frequently
when a user re-logs in after logging out from the app. I'm using
Cookies to store the session information. What am I doing wrong, I
presume the issue is that a session id that the user has in a cookie
isn't valid when they get bounced from the login page because
they're crossing instances?
Thanks

See below for how I kill the cookie to avoid this.
/**
* Method to handle terminating session upon logout (forced or
requested).
*/
public static void logout(com.webobjects.appserver.WOSession
session, WOResponse response)
{
/** require [valid_session] session != null;
[valid_response] response != null; **/
// Try to avoid deadlock when multiple requests came in for a
session that is getting terminated
// Ajax components can cause this
session
.setTimeOut
(WOApplication
.appProperties().intPropertyForKey("SessionTerminateTimeOutInSeconds"));
// This prevents WO from returning a cookie from the soon to
be expired session
// and instructs the browser to discard the cookie that it
has for the session
session.setStoresIDsInCookies(false);
if (response != null)
{
WOCookie killSession = new WOCookie("wosid", ".", "/",
null, 0, true);
response.addCookie(killSession);
}
session.defaultEditingContext().revert();
}
