Tomcat maintians a reference count for each session which is increased at the beginning of a request and decreased at he end of the request. If - for whatever reason - this reference count does not reach zero after all requests have finished (e.g. because one thread was increasing while another was decreasing, or an exception occurred which is not propably handled or... ) tomcat will not invalidate the session because it thinks there is still some request currently running (which basically is a good thing. I do generally NOT want my session to expire while a request is still running: e.g. a large download ) But this is still only a theory - I need to find a few free minutes to implement a test case... -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
