Rails session still alive after db:drop
<p>I'm curious  why <code>session</code> left alive after <code>rake db:drop</code>?</p>

<p>I have </p>

<pre><code>  def current_order
    if !session[:order_id].nil?
     @current_order =  Order.find(session[:order_id])
    else
      Order.new
    end
  end
  helper_method :current_order
</code></pre>

<p>and after rake db:drop it gives me exception </p>

<pre><code>Couldn't find Order with 'id' = my session number
&gt;&gt; session[:order_id]
=&gt; 11
</code></pre>

<p>that means session still there. But Why?</p>
