Implement user authentication on a load balanced site without sticky sessions

Implement user authentication on a load balanced site without sticky sessions

I am trying to implement user authentication for my website that will sit
on multiple servers behind a load balancer. I am hoping there is some
secure method that I can use without having sticky sessions turned on at
the load balancer so the same users always hit the same server. Does
anyone have a solution for this? In research on this I see mentions of
using a DB that all servers will hit but I am unsure what sort of
information the user should store to send with each request once it has
been logged in. Just sending some sort of session id that is associated
with a particular user in the DB seems insecure. Or is it just normal to
use sticky sessions? I am worried what will happen to the users sessions
if a server dies or if the load is not able to spread out properly.
Thank you.
