Removing CURLOPT_FOLLOWLOCATION returns empty output
Hullo,
this weekend the parsing of a web page stopped working perhaps due to a restyling of the site. The page is:
http://muovi.roma.it/paline/palina/77113?nav=4

and I m trying to parse it with the following function:
PHP Code:
function atac_get_html($url$language){
$url='http://muovi.roma.it/paline/palina/77113?nav=4'//manual forcing
    
set_include_path("/iPhone/simplehtmldom_1_5");
    require_once(
'simple_html_dom.php');
    require_once(
'atacurl.php');
    
// Create DOM from URL or file
    //$atacurl=atacurl();
    //$languageUrl=$atacurl."/lingua/set/".$language;

$languageUrl=http://muovi.roma.it/lingua/set/en";
    
if (!isset($_SESSION['ckfile'])) {
echo 
"language".$languageUrl;
        
$ckfile tempnam ("/tmp""CURLCOOKIE");
        
$_SESSION['ckfile']=$ckfile;
/* STEP 2. visit the homepage to set the cookie properly */
        
$ch curl_init ($languageUrl);
        
curl_setopt ($chCURLOPT_COOKIEJAR$ckfile); 
        
curl_setopt ($chCURLOPT_RETURNTRANSFERtrue);
        
curl_setopt($chCURLOPT_FOLLOWLOCATION1);
        
$output curl_exec ($ch);
//echo "outputInit=".$output."
";
    }
    $ckfile=$_SESSION['ckfile'];
/* STEP 3. visit cookiepage.php */
    $ch = curl_init ($url);
    curl_setopt ($ch, CURLOPT_COOKIEFILE, $ckfile); 
    curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
    $output = curl_exec ($ch);
    curl_close( $ch );
echo $url;
echo "
output=".$output;
    return str_get_html($output);

Yet, when I execute it, instead of going to the url page it goes to the home. What is quite peculiar is that, if I remove the latter curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true), I have an empty output like the page had a refresh setting that does not manifest itself when connecting by a browser but it does if trying to parse it! I am totally puzzled and unfortunately that piece of code is at the core of an iOS app I have on production and so I am also quite in a hurry.
Could someone please help,

Thanks,
Fabrizio Bartolomucci

RE: Removing CURLOPT_FOLLOWLOCATION returns empty output
This forum is not for the famous cURL (libcurl), Curl is a "UX" language, for building cool client applications Smile running on windows, linux and mac , so I think maybe you want to ask here:
http://curl.haxx.se/
