Description:
------------
My environment is an IIS/6.0 on a Win2K system with PHP4.4.0.

When trying to forward a request to another PHP script using the header( 'Location: ...' ) function, the following error occurs:

----------------------------------
CGI Error
The specified CGI application misbehaved by not returning a complete set of HTTP headers.
----------------------------------

This error only occurs if:
- the target script is a PHP script INCLUDING PHP code
- the source script has been connected to an Oracle DB with a PERSISTENT connection (I know it does not make that many sense to use it under CGI. anyway.)
- web server is running PHP in CGI mode

Btw: I also tried to play around with php.ini settings of fastcgi.impersonate and cgi.rfc2616_headers which did not help either. Current setting for these are 
fastcgi.impersonate = 1
cgi.rfc2616_headers (DEFAULT, because not set)

I have also tried hints described in PHP Bug 9852 and 8744 without positiv results.

Reproduce code:
---------------
try to use the following files to reproduce the error:

----------- forward.php ----------
<?
$connection	= OCIPLogon( 'user', 'passwd', 'host');

header( 'Location: target.php?'.rand() );
?>
----------- /forward.php ----------


----------- target.php ----------
<? echo 'it works'; ?>
----------- /target.php ----------


Expected result:
----------------
it works

Actual result:
--------------
CGI Error
The specified CGI application misbehaved by not returning a complete set of HTTP headers.
