How to download multiple files in one shot in IE

I want to download multiple files on click of a button in jsp.
I am using the following code in the js to call one servlet twice.

var iframe = document.c

I had a similar need but also wanted the downloads to occur in a new window.

I created a js to download a list of files, and a php to do the actual file saving. I used the above as a starting point, and the PHP start from (okay, can't find the original source). I encode the passed URI so spaces in the file names don't cause troubles.

(function () {
"use strict";

var files = [],              // Array of filename strings to download
newWindow,                   // New window to handle the download request
secondsBetweenDownloads;     // Wait time beteen downloads in seconds
//
//  Download a file using a new window given a URI
//
  function downloadFile(uri) {
    if (!newWindow) {
        newWindow = window.open('',
            '',
            'width=1500 height=100');
    }
    if (newWindow) {
        newWindow.location =
            'saveAs.php?' +
            'file_source=' + encodeURI(uri);
        newWindow.document.title = "Download File: " + uri;
    } else {
        console.log("Unable to open new window.  Popups blocked?");
    }
}
//
//  Download all files specified in the files[] array from siteName.
//  Download the file at array position zero, then set a timeout for
//  secondsBetweenDownloads seconds
//
function downloadFiles(siteName) {
    var showTime = new Date();

    console.log(
            showTime.toTimeString().substring(0,8)  +
            " Starting download for: " + files[0]
        );
    // Skip any empty entries, download this file
    if (files[0].length > 0) downloadFile(siteName + files.splice(0, 1));  
    if (files.length > 0) {                     // If more files in array
             window.setTimeout(function () {    // Then setup for another iteration
                downloadFiles(siteName );
            }, secondsBetweenDownloads * 1000); // Delay for n seconds between requests
     } else {
        newWindow.close();                      // Finished, close the download window
     }
}
//
//  Set the web site name and fill the files[] array with the files to download
//  then kick off the download of the files.
//
$(document).ready(function () {
    var
    siteName** = "http://www.mysteryshows.com/thank-you/";
    secondsBetweenDownloads** = 35;   // N seconds delay between requests

    files = [
        "show1.mp3",
        "show2.mp3"
   ];
    downloadFiles(siteName, files);
});
}());

The HTML for the page is simple. Basically any syntax-compliant page will do.

The saveAs.php page which the js file uses in the newWindow.location line is php only.

I used rawurlencode on just the 'basename' portion of the URI to ensure it was a valid, encoded request.
