Memcache session store in Rails 3

Hi everyone,

I found a guide to config session store using memcache-client in Rails
2.x. However, it seems config files were changed in Rails 3, and I'm
quite confused how to make these things work on Rails 3. Googled and
found no guide on configuring memcache session in Rails 3.

Thanks for help.

Here the guide link for Rails 2.x
