 [2003-06-02 04:53 UTC] drigolin at iol dot it 
Using this code: 

<?php
exec("online.bat param1");
header("Location:http://myserver/mypage.php");
exit;
?>

my browsers (IE and Mozilla) instead of do a redirect they display this message:

Status: 302
Content-type: text/html
X-Powered-By: PHP/4.3.1
Location:http://myserver/mypage.php

That is the full "dump" of the HTTP header of a Redirect (302) but it seems that exec() put into output stream any char that causes browsers to misunderstand the header and consider it an "raw text output".

Commenting exec or calling other function makes the script working correctly and the browser works ok.

Best regards.

P.S.: PHP is working as CGI on Netscape iPlanet Web Server.

Thank you for taking the time to report a problem with PHP.
Unfortunately you are not using a current version of PHP -- 
the problem might already be fixed. Please download a new
PHP version from http://www.php.net/downloads.php

If you are able to reproduce the bug with one of the latest
versions of PHP, please change the PHP version on this bug report
to the version you tested and change the status back to "Open".
Again, thank you for your continued support of PHP.

4.3.2 was release already.
