Is there a way to store data for separate users in Drupal without using sessions. I have previously used Drupal varibales. But it didin't work because the variable gets updated for every user (So whenever I access the variable it shows the last users details). I can't use sessions because I have a horizontally scaled server, so when the server is changed the sessions will be deleted.
Is there a way to do this exactly as the sessions but without sessions? I need to save users data in the browser temporarily.
