Operating system: Mandrake 9.1
PHP version: 4.3.3
PHP Bug Type: HTTP related
Bug description: Strange behaviour of header() function
Description:
------------
Hello.
I'm not sure whether this is a bug or a configuration error, but it has me
stumped. I've searched the bugs and can't quite find anything exactly the
same. Ironically, a number of people have complained about 'Location: '
not working, but it works perfectly here, and that's not what my problem
is.
Operating system is Mandrake 9.1. Web Server is Apache 1.38 with php 4.3.3
(problem occurs whether either statically compiled-in or as dynamic .so
using apxs), with mod_perl 1.28 as a dynamic .so under apxs (problem
occurs whether this is loaded or not). Problem occurs whether using
php.ini-dist or a customised version. All ingredients compiled from
source.
I was trying to change some of the headers. The production code is massive
and unwieldy, but managed to display the same symptoms with code
reproduced below.
In short: On a normal request the server reponds as follows:
HTTP/1.1 200 OK
Date: Thu, 16 Oct 2003 15:44:22 GMT
Server: Apache/1.3.28 (Unix) mod_perl/1.28 PHP/4.3.3
X-Powered-By: PHP/4.3.3
Connection: close
Content-Type: text/html
However, trying to change *any* of the headers that are already present
fails. This fails whether you specify the boolean 'append' value or not
(if not, nothing is changed, if you specify 'appended', nothing is added).
Adding other headers works perfectly fine, but trying to change those
already present does not.
Using the code provided the server returns this:
HTTP/1.1 200 OK
Date: Thu, 16 Oct 2003 16:07:54 GMT
Server: Apache/1.3.28 (Unix) mod_perl/1.28 PHP/4.3.3
X-Powered-By: PHP/4.3.3
Foo: Bar
Monkey: Nuts
Connection: close
Content-Type: text/html
The new headers are added perfectly correctly, but the old ones are not
altered at all. Is is just that these two headers are unalterable, is this
a bug, or could it be a configuration issue?
Reproduce code:
---------------
<?php
//change headers (older date, different server)
header('Server: Monkey/1.0');
header('Date: Mon, 18 Nov 2002 11:24:52 GMT');
//add other headers for testing...
header("Foo: Bar");
header("Monkey: Nuts");
?>
