HTTP Authentication

[tuf-web_co_uk]

i'm using a script to log out of http authentication however when i go back to the admin page it is still logged in

i've read somewhere that the browser automatically sends the information again.

but i also know that my hosts cpanel uses http authentication and i am able to log out of that.

any ideas on how to log out of http auth?

thanks,
Jon

try something like

function logged_in() {
  if (!empty($_GET['logout']))
    $_SERVER['PHP_AUTH_USER'] = false;
  return $_SERVER['PHP_AUTH_USER'] !== false;
}

to log out the user

<a href="index.php?logout=1">Logout</a>

to check

if (!logged_in()) {
  header('WWW-Authenticate: Basic realm="My secret room"');
  header('HTTP/1.0 401 Unauthorized');
  header('status: 401 Unauthorized');
}

not sure but maybe it will work

however when i try mypage.php?logout=1
i get the http auth form, but i cant log in

code

<?
function logged_in() { 
  if (!empty($_GET['logout'])) {
    $_SERVER['PHP_AUTH_USER'] = false; 
  }
  return $_SERVER['PHP_AUTH_USER'] !== false; 
}


if (!logged_in()) {
    header('WWW-Authenticate: Basic realm="theutherfish.com : Admin"');
    header('HTTP/1.0 401 Unauthorized');
    echo '<h2>ERROR : You Must Log In To Access The Control Panel</h2>';
    exit;
} 
else {

$dblink=mysql_connect($dbserver,$dbreaduser,$dbreadpass);
$db_sel = mysql_select_db($db) or die("Query failed: " . mysql_error());
$query="SELECT `password` FROM ".$usertable." WHERE username = '".$_SERVER['PHP_AUTH_USER']."'";
$queryresult = mysql_query($query,$dblink) or die(mysql_error());			
$row = mysql_fetch_array($queryresult);

if (md5($_SERVER['PHP_AUTH_PW']) == $row['password']) {

}

else {

	header('WWW-Authenticate: Basic realm="theutherfish.com : Admin"');
	header('HTTP/1.0 401 Unauthorized');
	echo '<h2>ERROR : You Must Log In To Access The Control Panel</h2>';
	exit;

}

}

?>
