Summary: Problem with Request-->redirect

Initial Comment:
Hello,

As I moved from a Windows 2000 to a Windows 2003 
server, I got some problem with the redirect function.

I am running PhpWiki under IIS6.
 (things are working relatively well if we except 
this problem, and a logout problem that I mentionned 
previously).

I use the latest version of PHP 5.  (5.12 I believe).

Here is the problem I have:

I have 
DISABLE_HTTP_REDIRECT set to true.

(when I set DISABLE_HTTP_REDIRECT to false the system 
works).

When I update a page, and after I click on the Save 
button, the system never returns.
When I stop the browser and look at the page, I can 
see that my page has been correctly updated.


I spent sometime trying to figure out what was the 
problem (Initially I though about a bug with IIS6 and 
the http redirect, but other tests have shown me that 
http redirect work).

The problem seems to originate in Request.php

function redirect($url, $noreturn = true) {
    $bogus = defined('DISABLE_HTTP_REDIRECT') && 
DISABLE_HTTP_REDIRECT;

if (!$bogus) {
    header("Location: $url");
    ....
}

if ($noreturn) {
     $this->discardOutput(); // This might print the 
gzip headers. Not good.
     $this->buffer_output(false);

     include_once('lib/Template.php');
     $tmpl = new Template('redirect', $this, array
('REDIRECT_URL' => $url));
     $tmpl->printXML();  ===>  #### BLOCKED ####

     $this->finish();  ==> not executed ????
}
 ...

}


As a workaround, I have commented the $tmpl->printXML
();.

I do not know what this redirect template is about.
(could be good to have a few more comments in the 
code)


Thierry.
