title: Using rack-timeout gem on Rails
body: <p>I'm trying to use the <a href="https://github.com/kch/rack-timeout" rel="noreferrer">rack-timeout gem</a> on Rails. I added the line <code>gem 'rack-timeout'</code> to my Gemfile and ran <code>bundle install</code>. (It shows <code>Using rack-timeout (0.0.4)</code>) Then I submitted a request to my server. It clearly hung for more than 15 seconds without returning anything to me. What am I missing?</p>
