How do sessions work in Ruby on Rails?

Question

I want to know how sessions work in Ruby on Rails.

I already now that I can save a session with session[:user_id] = @user.id and retrieve it with session[:user_id].

Thus, does Rails save the session to cookie store, cache store, or database store?

Session is stored in cookies by default. But you can change it to cache or database if you need. — Santhosh, Jun 09 '15 at 06:45

Sessions are kept serverside. It's saved on the webserver itself. This can be in a file/memory/database. The ID of that session is saved in a cookie on the user his browser to associate the user with the correct session.
