Description

The method for retrieving headers is not complete so when the method apache_request_headers() is not available false will be returned on some systems

This happens when the $SERVER does not contains 'HTTP_CONTENT_TYPE' but 'CONTENT_TYPE', since the system looks for HTTP + requestvar.

(line 950)

$temp = 'HTTP_' . strtoupper(str_replace('-', '_', $header)); if (!empty($_SERVER[$temp])) { return $_SERVER[$temp]; }

After the above the following could be added $temp = strtoupper(str_replace('-', '_', $header)); if (!empty($_SERVER[$temp])) { return $_SERVER[$temp]; }

The issue here is that CONTENT_TYPE and CONTENT_LENGTH are not prefixed with HTTP_. The reason is because CONTENT_TYPE and CONTENT_LENGTH are not protocol specific meta-variables (http://www.ietf.org/rfc/rfc3875).

So, unless you have the apache_request_headers method available, the type and length of the request are never obtained for the request.

Never say, "never".

The current test in Zend_Controller_Request_HttpTest::testGetHeader() has

<pre class="highlight">
$_SERVER['HTTP_CONTENT_TYPE']    = 'text/json';

So it would seem some PHP environments do put HTTP_CONTENT_TYPE in $_SERVER.

I'm not sure what the appropriate patch to Zend_Controller_Request_Http is, but I know I add this to dispatch script (public/index.php).

<pre class="highlight">
if (isset($_SERVER['CONTENT_TYPE'])
    && !isset($_SERVER['HTTP_CONTENT_TYPE'])
) {
    $_SERVER['HTTP_CONTENT_TYPE'] = $_SERVER['CONTENT_TYPE'];
}

I'd be interested to find out what environments return HTTP_CONTENT_TYPE.

In regards to a patch for HTTP requests, I would say we try to load the requested meta variable without the HTTP prefix, then if not found, add the HTTP prefix and try that.

I'm experiencing it on Windows XP with Apache 2.2/PHP5.3.x.

Have you found an issue?
