Description:
------------
In 'HTTP/1.1 304 Not Modified' response from PHP script where is a 'Content-Type: text/html'. 

rfc2616 tell us:

"The 304 response MUST NOT contain a message-body, and thus is always terminated by the first empty line after the header fields."

I have read the discussioan about simular Bug #3299, but I think Apache response is correct rather than PHP.

Reproduce code:
---------------
<?
header('HTTP/1.1 304 Not Modified');
header("Cache-Control: max-age=".($expire-$last_modified));
header("Expires: ".gmdate('D, d M Y H:i:s',$expire)." GMT");
?>

Expected result:
----------------
HTTP/1.1 304 Not Modified
Date: Mon, 08 Dec 2003 12:03:27 GMT
Server: Apache/1.3.28 (Unix) PHP/4.3.4
Connection: close
ETag: "49621b-10ca-3fd43c1b"
Expires: Tue, 07 Dec 2004 12:03:27 GMT
Cache-Control: max-age=31536000

(apache response from request to plain html file, without PHP).

Actual result:
--------------
HTTP/1.1 304 Not Modified
Date: Mon, 08 Dec 2003 12:15:05 GMT
Server: Apache/1.3.28 (Unix) PHP/4.3.4
