Finding the session id in rails 3

Have you tried the following?

request.session_options[:id]

It also returns the session ID:

session[:session_id]

If you need to see data written in Session store for given session id from Rails console you can:

a = Rails.application.config.session_store.new(app, Rails.application.config.session_options)
a.class # => ActionDispatch::Session::RedisStore
a.get_session(ENV, '07319b2485be9ac4850664cd47cede38')


# or a.find_session(ENV, '07319b2485be9ac4850664cd47cede38')

app andENV are set when you start rails console, don't need to set those

you can get the session_id via some a browser plugin dealing with cookies or (cookie inspector, cookies manager, ...)

I can't test it right now but as far as I know the session id variable changed from 'id' to 'session_id' on Rails 3, have you tried that one? Hope it works for you.
