Ok you scripting brainiacs..here's one for you

[carefree2]

login.php

$come_from = $_SERVER['HTTP_REFERER'];

if ($come_from == "site.com/login.php"){

$redirect_url = $config['baseurl'] . '/' . $user_info['user_name'];

}else{

$redirect_url = javascript:history.go(-2);

 redirect($redirect_url)

}

$_SERVER['HTTP_REFERER'] isnt the best tracker to use for internal pages but the if else will prevent any bugs
