Hello, It is probably me but it seems like the build-in HTTP server does not well support the HEAD method. Here is my following test case. First, the foo.php file:

    <?php

    var_dump($_SERVER['REQUEST_METHOD']);

By definition, a HEAD request MUST NOT return a message-body. Oh grrr, I feel stupid now ;-). I forget this.

This works as expected: <?php header("X-Request-Method: " . $_SERVER["REQUEST_METHOD"]); ?> Here is how it works: main/SAPI.c has code that set SG(request_info).headers_only = 1 for HEAD requests, and as a consequence php_request_shutdown() does not flush the output buffer (if any) to the client. Ok.

You can force a body to be sent (but that's likely not going to work with every SAPI) by not having an output buffer or by calling ob_end_flush() yourself. Yes but that was not my goal.
