title: Rails 3: redirect_to with :remote => true
body: <p>I have a delete link that makes a remote call:</p>
  
  <pre><code>&lt;%= link_to image_tag("trash.png"), [current_user, bookcase], method:  :delete, :remote =&gt; true, confirm: "You sure?", title:   bookcase.image %&gt;
  </code></pre>
  
  <p>In my controller, I end the delete function with a redirect:</p>
  
  <pre><code>def destroy
    @bookcase.destroy
    redirect_to current_user
  end
  </code></pre>
  
  <p>This works, except it's redirecting the user to the 'user/show.html.erb' file instead of the 'user/show.js.erb' file. How can I redirect the user, specifying which format to use?</p>
