Last time I posted an ASP and bound multiple domain names to one space without affecting each other. It was very popular.
$domain_net="abc.com";
$dot_net_url="bbs/";
$dot_com_url="flash";
if(($HTTP_HOST=="$domain_net" )or($HTTP_HOST=="www.$domain_net"))
{
Header("Location: $dot_net_url");
}
else
{
Header(" Location: $dot_com_url");
}
?>
