can't set the timeout of session variables up to 20 minutes

i would like to set the timeout of my session variables to 6 hours, but after 20 minutes
(default in cf-administrator is 10 seconds) they timed out.

i tried to set it directly in my 'cfapplication - tag' with 'sessionTimeOut="#CreateTimeSpan(0,0,30,0)#"'
(for testing i set the timeout to 30 min) but it also timed out after 20 minutes.

when i set the timeout for example to 'sessionTimeOut="#CreateTimeSpan(0,0,0,10)#"' (10 seconds) then it works....

thanks for all ideas...

The default timeout in the CFADMIN may be 10 seconds, but what is the MAXIMUM timout? It's to the left of the default. If this is set to 20 minutes, then you can never set the timeout greater than that. Try checking there first.

Try setting the Application timeout to 15 minutes and it should work, setting it to 25 will not then.
Whatever you set in your APPLICATION.CFM page will never be longer than what has been set in Administration. It can be shorter, but never longer.

You must extend the timeout in Administration to see any effect from what you have set in your APPLICATION.cfm.

If you do not have access to Administration, the only option that comes to mind is to set a META tag with a refresh rate of about 19 minutes.  This way if a page just sits and the user does nothing for 19 minutes, the page will refresh itself and reset the session timer.

<meta http-equiv="REFRESH" content="19; url=/index.cfm">

Try to add the parameter ApplicationTimeOut for your <cfapplication> tag. Setting it to a desired time span for your default value of your ColdFusion Administrator.

thanks for your answers...

shame on me. i made a beginner's mistake.
for info:
in cf-admin i have set the maximum timeout to
'12 hours' and the minimum timeout to '10 seconds',
but i haven't restarted the cf-server...
so the defaults for the maximum and minimum timeouts were
still set - '20 minutes'.

when i tried to set the timeout to e.g. '10 minutes' in the 'cfapplication-tag', it worked fine, because the 'cfapplication-tag' overrides the default 'minimum
when i tried to set the timeout to e.g. '30 minutes' in the 'cfapplication-tag', it didn't work, because the 'cfapplication-tag' doesn't override the default 'maximum

the lesson of my problem ->
when you are updating your timeouts for the session variables, RESTART your cf-server!!!
