session redirect HELP

[justinede]

what do i change to this code to put on my index so if there loged in already it just goes to index1.html

 

<?

session_start();

if(!session_is_registered(myusername)){

header("location:index.html");

}

?>

 

that makes it so if they try to go to index1 it send them to index to login. but if there already logged in what makes them go to index1.html
