Cucumber: how to switch sessions in Rails (multi-session)

I need to change session during one cucumb开发者_开发技巧er scenario.

For example

Given session name is "1st unauthenticated user"
And make some things
Given session name is "2st unauthenticated user"
And make some other things

I found a solution, but it doesn't work with Rails 3, Cucumber and Capybara. Are there any other solutions?
