Problem with creating php proxy

I can't get this to work:

<?php
    $url = 'http://someServer.com/save.asp?';

    $count = 0;

    foreach($_POST as $key=>$value) 
    {

        if( $count != 0 ) $url .= "&";

        $url .= urlencode($key).'='.urlencode($value);

        $count++;

    } 

?>
<html>
<head>
<meta http-equiv="refresh" content="0;url=<?php echo $url;?>">
</head>
<body>
</body>
</html>

If I copy the output of the final $url string and paste it in directly in the browser, it works fine.

So it looks like the $url gets built correctly, but there is some problem with the redirection.

// EDIT

I am trying to get this to work:

<?php 


$str = '';

$count = 0;

foreach($_POST as $key=>$value) 
{
    if( $count != 0 ) $str .= "&";

    //$url .= urlencode($key).'='.urlencode($value);
    $str .= $key.'='.$value;

    $count++;
} 


$url = 'http://someDomain.com/acript.asp?'.$str; 


$agent= 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.0.3705; .NET CLR 1.1.4322)';

$ch = curl_init();
curl_setopt($ch, CURLOPT_VERBOSE, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERAGENT, $agent);
curl_setopt($ch, CURLOPT_URL,$url);
$result=curl_exec($ch);
var_dump($result);

?>

I get: Bad Request

Ah, your cURL is overly complex, it uses cookies and headers that indicate the request is expecting a an image. simply try this instead:

$agent= 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.0.3705; .NET CLR 1.1.4322)';

$ch = curl_init();
curl_setopt($ch, CURLOPT_VERBOSE, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERAGENT, $agent);
curl_setopt($ch, CURLOPT_URL,$url);
$result=curl_exec($ch);
var_dump($result);

if this still doesn't work, just use firebug to see what are the headers you browser is sending and add them, like this:

$headers = array("Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8","Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7");

curl_setopt($ch, CURLOPT_HTTPHEADER,$headers);

If you want this to work, without relying on the browser to request the page, remove all the HTML and add:

print file_get_contents($url);

at the end. if this doesn't work for you (and it may not work for sevral reasons) you will have to use - http://php.net/manual/en/book.curl.php.

Also to build the right url, you don't have to iterate over $_POST yourself, use: http://php.net/manual/en/function.http-build-query.php

PS what ever you are trying to do, this is probably the wrong solution.
