file_get_contents('php://input') returning empty string with a PUT request

Question

After moving one of our websites from Linux with Apache to Windows with IIS (8.5) running PHP 5.6 via FastCGI, we've run into the problem that file_get_contents('php://input') returns an empty string for PUT requests.

I've created the following test:

<?php
if (!empty($_SERVER['HTTP_X_REQUESTED_WITH']) && 
    strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest') {
    die(file_get_contents('php://input'));
}
?>
<!DOCTYPE html>
<html>
<head>
    <script src="//code.jquery.com/jquery-2.1.3.min.js"></script>
</head>
<body>
    <h2>POST:</h2>
    <div id="post"></div>

    <h2>PUT:</h2>
    <div id="put"></div>
    <script>
        $.ajax({
            url: '?',
            data: 'Working',
            type: 'POST'
        }).then(function(response) {
            $('#post').html(response || 'Not working');
        });

        $.ajax({
            url: '?',
            data: 'Working',
            type: 'PUT'
        }).then(function(response) {
            $('#put').html(response || 'Not working');
        });
    </script>
</body>
</html>

Which results in:

POST:

Working

PUT:

Not working

What could be causing this?

maybe conflicts with IIS WebDAV-module. Also check 'Handler Mappings' options. — Deadooshka

As it turns out the problem is caused by the Helicon Ape module (a module for supporting Apache .htaccess and .htpasswd configuration files). Removing this module fixes the problem, but I still don't know why it would interfere with PUT requests. I guess I'll have to post a topic on their forum with this issue.
