If you are using database sessions, rails sessions table stores session information in “sessions” table that contains two columns: “session_id” and “data”.
Now, if you need to know the session_id of current session your first instinct would be to do the following:

session.session_id

This will not work since session is just hash containing name/value pairs and not an ActiveRecord object. So what do we do introspect session’s own information.

Solution: We use “request.session_options”. It is a hash that contains session_id and a few more options related to session.

request.session_options.inspect ={:secure=>false, :secret=>"ZBYULTOIJYLYWVNONXNSWUJCKMVVFPIZCEEGDAIE", :expire_after=>nil, :key=>"_SOMEGT_session", :id=>"4d4999d4650f4b21121c8f2b65917fac", :cookie_only=>true, :httponly=>true, :path=>"/", :domain=>nil}

Here :id is the session_id and :key is the cookie name under which it stores the session_id.

Now I know.
