This is what I don't understand... I have the CF Admin settings set to 20 mins for the session life. The JSEE sessions were set at 30 mins and I saw lots of errors. I've now increased the time to 35 minutes and although the errors are reduced in number, they still happen... As you have stated the issue, the errors should not have happened in the first place with our setup and increasing the J2EE session timeout by a further 5 minutes seems like an odd way to reduce the errors we've seen but, nevertheless, that is what it has done. I'm thinking this may be a timing issue on multi-CPU deployments. I remember back in the day looking at task manager stats where the System Idle time would read close to 48 hours when the server was re-booted 24 hours previously because the clock was accounting for the idle time on both processors... I wonder if the JRun session timeout process is looking at a ticker in the system that is effectively halving/quartering etc. the entered value in relation to the number of processors in the system and causing these timing anomalies? The idea (in my mind at least) has merit. > Second, the JSESSION cookie is the only one used for J2EE sessions. > The CFID and CFTOKEN cookies are used for client variables; you can > prevent them from being set for new users with the setClientCookies > setting in your application tag/cfc (set it to false). That sorts out that bit. Thanks!
