title: Cookie & Escaping: Store comma separated List in a Cookie
body: <p>I want to store 3 values in one cookie - comma separated.
  I tried this:</p>
  
  <pre><code>cookies[:location] = "#{params[:lat]},#{params[:lon]},#{params[:city]}"
  </code></pre>
  
  <p>the commas get escaped. Resulting in something like "%2C..."
  I tried different ways with <code>html_safe</code>, <code>raw</code> and so on, but i with no success.
  What am i doing wrong here? How can i create a single cookie with three or more values separated by comma?</p>
