After redirect session data null ---solved

[eluser]sayed[/eluser]
Hi,
I was facing a weird problem in CI. My CI code was same but few days later when I permit more permission to a user it doesn't not longing. After lots of struggling I found the problem. Problem was when I redirect the controller after pushing all the permission to session, it just null my session values. Problem is CI session variable may not contain more data(memory size issue). Now I solved this by distributing my permission data.Like when I redirect to a controller,that controller load its own permission for logged in user. If any one face this issue(CI session variable memori limit) and solved other way please share.

thanks.
