title: Handle sessions with load balancer?
body: <p>Maybe this is obvious but if i have a load balancer or multiple servers in use, the user's session is coming from 1 server so if the user is pushed to say server 2 or server 3 then does that mean the user's session will expire or how to make it work as normal? </p>
  
  <p>I have multi-session checks, so if a user logs-in from a different location it will auto sig them out like we see on bank websites. Does this effect servers? Is there anything I need to do at the database level?</p>
  
  <p>EDIT:
  Using PHP codeignitor. Currently i have 1 dedicated server but in the process of adding 2 more servers hence before I add those I need to know if sessions will work or if it requires re-doing the session code again.</p>
