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']);


And then:

    $ # Run the server.
    $ php -S 127.0.0.1:8888 -t . foo.php > /dev/null 2>&1 &

    $ # Test with POST.
    $ curl -v -X POST 127.0.0.1:8888
    * About to connect() to 127.0.0.1 port 8888 (#0)
    *   Trying 127.0.0.1...
    * connected
    * Connected to 127.0.0.1 (127.0.0.1) port 8888 (#0)
     > POST / HTTP/1.1
     > User-Agent: curl/7.24.0 (...) libcurl/7.24.0 OpenSSL/0.9.8r
    zlib/1.2.5
     > Host: 127.0.0.1:8888
     > Accept: */*
     >
    < HTTP/1.1 200 OK
    < Host: 127.0.0.1:8888
    < Connection: close
    < X-Powered-By: PHP/5.5.0-dev
    < Content-type: text/html
    <
    string(4) "POST"
    * Closing connection #0
    $ # It works, cool.

    $ # Now, test with HEAD.
    $ curl -v -X HEAD 127.0.0.1:8888
    * About to connect() to 127.0.0.1 port 8888 (#0)
    *   Trying 127.0.0.1...
    * connected
    * Connected to 127.0.0.1 (127.0.0.1) port 8888 (#0)

I have to admit that I don't understand, even by looking at the source code.

Thoughts?
Thanks.
