title: Download multiple files with a single action
body: <p>I am not sure if this is possible using standard web technologies.</p>
  
  <p>I want the user to be able to download multiple files in a single action. That is click check boxes next to the files, and then get all the files that were checked.</p>
  
  <p>Is it possible - if so what basic strategy do you recommend. I know I can use comets technology to create server side events that trigger an HttpResponse but I am hoping there is a simpler way. </p>
