redirect to different page according user group

hi
i want use cbAutoAction redirect type(or use your suggestion) to redirect user to different menu according user group.
for example if userA in Jusergroup1 then redirect onAfterLogin to JMenu 1 and if he is in the Jusergroup2 then redirect to JMenu 2 and ...
how to implement that with CB auto action system?

Create two auto actions with Triggers set to onAfterLogin, set Type to Redirect, then adjust the Access parameter according to your needs. Leave everything else under Global at their default values. Next under Action specify your redirect; your URL should be non-SEF and begin with index.php.

thank you kyle but my problem is i have more than two autoaction and i guess you say in the past, same autoaction type have not good performance.
i have 5 onafterlogin action . infact i have 5 Jusergroup that i want when they login, redirect to different 5 menu.
need to create 5 autoaction?

You can have as many auto actions as you want. What you're trying to do isn't heavy and should have little to no impact on performance. There would be no issues with having 5 auto actions as you're needing.
