title: Multiple file upload compatible with Internet Explorer
body: <p>I would like to have an upload control on an intranet website, which needs to support multiple file upload. Drag and drop is not required, I just want to select a lot of files (in hundreds, possibly) for processing on the server. After the uploads are complete the user will be redirected to another page where he'll be able to process the results. </p>
  
  <p>I'd also like to support other browsers, but IE is the most important as most of the customers use it as per their IT policy and it cannot be changed. Their computers are restricted enough and Silverlight might be the way as it's official Microsoft plugin, compared with Flash.</p>
  
  <p>I would like to have a form with a “Browse” button which allows the user to pick files, then the file names are added to a list and “Upload” button that starts the upload to a server side code that saves the file somewhere and redirects the user to the next page.</p>
  
  <p>I think that I should use Silverlight for IE7/8/9 and HTML5 for Firefox, Safari, Chrome and Opera (and IE10, eventually). That would mean coding two separate (html5+silverlight) front-ends and one common back-end on the server. </p>
  
  <p><em>I know</em> that Telerik has <a href="http://demos.telerik.com/aspnet-ajax/upload/examples/async/multiplefileselection/defaultcs.aspx" rel="nofollow">something exactly like this</a> and works, but it's too expensive as I need only one control of their library. </p>
  
  <p>Is there something open-source that works this way? Or is there a better and simpler way to support IE and HTML5 file-compliant browsers?</p>
