<?
if($REQUEST_METHOD=="POST")
	{
	print($REMOTE_USER);
	}

print($REMOTE_USER);
print("<FORM ACTION='./essai.phtml' METHOD='POST' ENCTYPE='x-www-form-urlencoded'>");
print("<input type=TEXT name=TEXT size=50><br>");
print("<input type=submit name=Submit value='clic !'></font>");
?>

if I run this in a protected (.htaccess) dir, as it is, I loose $REMOTE_USER once I have filled and clicked.

If I use method 'GET', it works. I am almost sure it is a bug, non ?
