Tricky rss to read with curl

Question

This website seems to expect a cookie named AspxAutoDetectCookieSupport, if it didn't find it it will redirect you to some cookie detection page, and it will stuck in a loop:

> curl -I -L http://maxhire.net/cp/?EA5E6F361D4364703D044F72

^C

So you need to set this cookie: AspxAutoDetectCookieSupport=1:

curl_setopt($ch, CURLOPT_COOKIE, 'AspxAutoDetectCookieSupport=1');

That solved the first problem, another problem came up, if you didn't set a value for the user-agent it will send you this page:

<html xmlns:atom="http://www.w3.org/2005/Atom">
<head><meta http-equiv="Content-Type" content="text/xml; charset=iso-8859-1" /><
title>
        Untitled Page
</title><link href="App_Themes/Default/Common.css" type="text/css" rel="styleshe
et" /><link href="App_Themes/Default/Container.css" type="text/css" rel="stylesh
eet" /><link href="App_Themes/Default/Content.css" type="text/css" rel="styleshe
et" /><link href="App_Themes/Default/Login.css" type="text/css" rel="stylesheet"
 /></head>
<body>
    <form name="form1" method="post" action="rssCurrentJobs.aspx?site=5E6F361D43
64703D044F72" id="form1">
<input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="/wEPDwUKMTc2MTg4
NDc4NmRk" />

    <div>

    </div>
    </form>
</body>
</html>

So add a user-agent value:

curl_setopt($ch, CURLOPT_USERAGENT, "SomeUserAgent");

Full code:

function url_get_contents ($Url) {

    if (!function_exists('curl_init')){ 
        die('CURL is not installed!');
    }

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $Url);
    curl_setopt($ch, CURLOPT_POST, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($ch, CURLOPT_USERAGENT, "SomeUserAgent");
    curl_setopt($ch, CURLOPT_COOKIE, 'AspxAutoDetectCookieSupport=1');
    $output = curl_exec($ch);
    curl_close($ch);
    return $output;
}
