//Bug in PHP 4.0.6
If output_buffer = On AND 
        session_start() AND 
	header("Location: ..) AND 
	no HTML output then
 	PHP sends no header

You expect the browser to redirect to Location URL.
What really happends depends on the browser:
- Netscape: waits a while and nothing happens
- IE: redirects to search engine
- Konqueror: connection lost
- Some browsers indicate empty document received

Work around: 
- when output buffering is on, then add blank line      before start of script
- switch output buffering off

Example PHP page excerpt:
<?php
session_start();

if (!isset($HTTP_COOKIE_VARS['CompanyID'])) {
	$Info = urlencode("Please log in.");
	header("Location: Login.php?Info=$Info");
	exit;
}

// More lines .....
?>

4.2.0's output related code differs from 4.1.1. Could you try snapshot?

Please report the result. Thanks.

I tried to follow the instructions in INSTALL.
Configure option --with-apxs was not working as this package was not installed on my machine.
As package apxs was not delivered with Mandrake 8.1 AND PHP 4.0.6 was running fine without this package it did not look required to me (maybe I am wrong).
I decided to take over the options as indicated by phpinfo() in php4.0.6.
After "make install" all files in /usr/lib/php were updated.
Directory /usr/lib contained a new binary of php (3.1 Mb).
However a new version of php module libphp4.so was not generated.
phpinfo() shows that 4.0.6 is still running on my system.

Try to intall from the beginning for both apache and php using source.

If you don't include modules, you should be able to install apache and php easily if you follow manual. If you have problem, ask to php-general or php-install list.

Report back if you still have problem if you have problem with CVS snapshot. Thanks.
