session in rails is a hash object  Hence any function available for clearing hash will work with sessions   session clear   or  if specific keys have to be destroyed   session delete key    Tested in rails 3 2  added  People have mentioned by session    is a bad idea   Regarding session clear  Lobati comments-  It looks like you re probably better off using reset session  than session clear   as it does some other cleaning up beyond what session clear does  Internally   reset session calls session destroy  which itself calls clear as well some other stuff
