How to handle the encoding request correctly?

Question

I have two websites: one with Lighttpd with PHP and the second with Apache, and none of these descriptors encode the transfer encoding correctly.

I am sending this request from my J2ME mobile device and there is no way to change this transfer type to any other.

Thus, my only way is to process the transmitted encoded requests in a different way. Any solution would be good as long as I can enable it on my CentOS server, where I can install and change everything that is needed.

So my question is: how to properly handle server-side encoded encoding request?

$input = file_get_contents('php://input');
$stdin = file_get_contents('php://stdin');

print "FILES: ";
print_r($_FILES);

print("<br>POST: ");
print_r($_POST);

print("<br>input: ".$input);
print("<br>stdin: ".$stdin);
