No, best I can suggest is set the session time to a shorter time so it expires their session quicker.

Sorry, don't understand what you're asking. You want to redirect after they login? or you want to redirect when they immediately visit your site? That's doable with the onAfterRender Joomla event, but I don't recommend doing this as there's little information to condition against.

i want redirect immediately visit my site.
i want if my user logged in from last page closing and session is not expire yet, then redirect to some menu that i want.and occur for each user 2 time.

i can't find onAfterRender in autoaction. are you mean onAfterRenderModule?
is this mean render the page?

It doesn't have to be listed to be used. Prefix all Joomla events with joomla_ (e.g. joomla_onAfterRender). onAfterRender is not listed because it's easy to cripple your site if used incorrectly.

is it work in autoaction if i type that manually?
or need to create my own plugin to do this?
