Redirect in the Cancel of an HTTP authentication

Okada

Hi,

I´d like to redirect to an url when the user clicks the Cancel option in an HTTP Authentication.

The code:

if (!isset($PHP_AUTH_USER)) {
header('WWW-Authenticate: Basic realm="Acceso restringido"');
header('HTTP/1.0 401 Unauthorized');

$host = $SERVER['HTTP_HOST'];
$uri = rtrim(dirname($SERVER['PHP_SELF']), '/\');
$extra = 'indice.php';
//echo "Location: http://$host$uri/$extra";
//HERE I WANT TO REDIRECT
exit;
}

I´ve tested with header("Location: http://$host$uri/$extra"); but it doesn´t work.

Another thing I´d like to know is if this login method is secure or not.

Thanks!

The usual problem people have with headers is that you can't output anything before they are sent. Not a space, not a carriage return and not a echo/print.

Okada

The commented echo outputs the path I want to reditect to...

Piranha

I can see that...

Nobody can help me? Maybe you, Piranha..

what do you mean it doesn't work, are you receiving errors?

for giggles, put ob_start(); as your FIRST line of code, so:

<?php
ob_start();

//follow with your other stuff

I mean it ignores de Authentification headers. It directly redirects.

Sorry, my english is not quite good, I don´t know the meaning of giggles...

Okada

i mean it ignores the Authentification heades (the dialog doesn´t appear) and only redirects.

He means...

Just for fun (giggles), put ob_start at the beginning of your code.

Okada

Thank you for the explanation. 😉

I´ve put that ob_start() and it continues happenning the same.

I can´t believe there isn´t a way to redirect...HELP!!

Okada

I´ve found a way:

echo ("<script> document.location = 'http://$host$uri/$extra'</script>");

but it´s a bit...how could I say? 😃
