if($_SESSION['loggedin']==1) $showlogin=0;
else $showlogin=1;
include_once "./login.php";

echo $_SESSION['usr']."<BR> Please wait while you are redirected.<BR>".
"You are being redirected to Homepage in 5 seconds";
exit;
}

}

?>
[/code]

The problem is:
if i include login.php and try to visit home.php the page comes as blank, while if i visit login.php with a direct function call to login form then it goes well and good. What to do?
