$ .get不返回Internet Explorer中的任何数据

Question

I'm using JQuery's $.get function to fetch a twitter feed and display it on my site. I have no idea why it seems to not be getting any data (i.e. code inside function(d) { ... } doesn't get called). It works fine in everything else I've tried. I have also used this code before with no problems, the only thing I can think of is that it is running through https.

(Note that for the example I've removed the twitter user id from the feed url)

JS:

    $.get('proxy.php?url=http://twitter.com/statuses/user_timeline/999999999.rss', function(d) {    
        $(d).find('item').each(function() {
            var theItem = $(this);
            var title = theItem.find('title').text();


            var date = new Date(theItem.find('pubDate').text());
            var alink = theItem.find('link').text();

            // code ommitted (inserts tweet into page)
        });
  });

proxy.php:

<?php
    // PHP Proxy
    // Loads a XML from any location. Used with Flash/Flex apps to bypass security restrictions
    // Author: Paulo Fierro
    // January 29, 2006
    // usage: proxy.php?url=http://mysite.com/myxml.xml

    $session = curl_init($_GET['url']);                    // Open the Curl session
    curl_setopt($session, CURLOPT_HEADER, false);          // Don't return HTTP headers
    curl_setopt($session, CURLOPT_RETURNTRANSFER, true);   // Do return the contents of the call
    $xml = curl_exec($session);                            // Make the call

    $seconds_to_cache = 300; // five mins (60 * 5)
    $ts = gmdate("D, d M Y H:i:s", time() + $seconds_to_cache) . " GMT";
    header("Expires: $ts");
    header("Pragma: cache");
    header("Cache-Control: maxage=$seconds_to_cache");
    //header("Content-Type: text/xml");   // Set the content type appropriately
    header("Content-Type: application/rss+xml");
    echo $xml;        // Spit out the xml
    curl_close($session); // And close the session
?>

Any ideas / help would be greatly appreciated

Figured it out. IE needs the content type to be set to text/xml. I changed the proxy.php script:

header("Content-Type: text/xml");

and that was all I needed.
