php_auth_user problem

Hello, I'm running W98, Apache 1.3.14 and Php4 as a module for apache. I would like to restrict webpages access using the variables php_auth_user and php_auth_pw with the function header(). Unfortunately when I try to read the values of the php_auth_ variables nothing appear... It looks like these variables do not keep the values they were assigned... For example here is a really simple programm that doesn't work with my configuration : <?php

    if(!isset($PHP_AUTH_USER)) {
    Header("WWW-Authenticate: Basic realm=\"My Realm\"");
    Header("HTTP/1.0 401 Unauthorized");
    echo "Text to send if user hits Cancel button\n";
    exit;
    } else {
    echo "Hello $PHP_AUTH_USER.<P>";
    echo "You entered $PHP_AUTH_PW as your password.<P>";
    }

?> Thanks, Claude _____________________________________________________________________________________ Get more from the Web. FREE MSN Explorer download : http://explorer.msn.com
