强制IE在加载时重新下载文本文件

Question

My JavaScript has an function that goes off onload that takes a .txt file and creates an array from it. The page works fine in Chrome, but doesn't update in IE -- IE seems to cache the .txt file and re-create the array from the cache, ignoring any updates made to the .txt. Is there any way to force IE to re-download the .txt before creating the array so that the user isn't working with an outdated version of the information?

edit: Code!! (changed the file pathname, all else is the same)

function createArray() {
    var txtFile = new XMLHttpRequest();
    txtFile.open("GET", "http://PATHNAME/names.txt", true);
    txtFile.onreadystatechange = function() {
        if (txtFile.readyState === 4) {
            if (txtFile.status === 200 || txtFile.status === 0) {
                nameArray = txtFile.responseText.split("\n");
            }
        }
    };
    txtFile.send(null);
}

Furthermore, the file is stored on the server, in the same folder as the page that the data displays on, which is one level above the JavaScripts folder. So the directories look like:

page.html
names.txt
SCRIPTS FOLDER
    array.js

获取请求缓存，强制它通过更改URL来获取新文件。

txtFile.open("GET", "http://PATHNAME/names.txt?ts=" + new Date().getTime(), true);
