JavaScript Redirect and PHP cURL

    I'm using cURL to login to an account and download .zip files automatically. I login just fine, but instead on downloading a file, I get back a "no JavaScript" page. I'd like to know if it is possible to get around it.

    The download links look like this: http://example.com/?download=1872&key=a6fc

    When I follow that link with CURL, I get this...

    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<meta http-equiv="Content-Script-Type" content="text/javascript">
<script type="text/javascript">
function getCookie(c_name) { // Local function for getting a cookie value
    if (document.cookie.length > 0) {
        c_start = document.cookie.indexOf(c_name + "=");
        if (c_start!=-1) {
        c_start=c_start + c_name.length + 1;
        c_end=document.cookie.indexOf(";", c_start);
        if (c_end==-1)
            c_end = document.cookie.length;
        return unescape(document.cookie.substring(c_start,c_end));
        }
    }
    return "";
}
function setCookie(c_name, value, expiredays) { // Local function for setting a value of a cookie
    var exdate = new Date();
    exdate.setDate(exdate.getDate()+expiredays);
    document.cookie = c_name + "=" + escape(value) + ((expiredays==null) ? "" : ";expires=" + exdate.toGMTString()) + ";path=/";
}
function getHostUri() {
    var loc = document.location;
    return loc.toString();
}
setCookie('YPF8827340282Jdskjhfiw_92893745918266', '555.57.247.198', 10);
try { 
    location.reload(true); 
} catch (err1) { 
    try { 
        location.reload(); 
    } catch (err2) { 
        location.href = getHostUri(); 
    } 
}

    And the relevant part of the code I am using is...

    $ch = curl_init();
curl_setopt($ch,CURLOPT_URL,$FileURL);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,TRUE);
curl_setopt($ch,CURLOPT_FOLLOWLOCATION,TRUE);
 curl_setopt($ch,CURLOPT_COOKIEJAR,$cookiefile);
$fp = fopen($FinalFile,'w+');
curl_setopt($ch,CURLOPT_FILE,$fp);
$data = curl_exec($ch);
fclose($fp);
curl_close($ch);
    PHP:
    Thank you in advance.

    Sounds like you're trying to download from a site filled with scripttardery, so unless you have a way to actually run javascript on the server (like using a server-side browser engine) you are likely SoL on using curl to download from that site.

    Though you MIGHT be able to reverse engineer their script by doing a normal download from them and grabbing all the .js it uses along the way.
