$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");
}
?>


再如：

$domain_net="sutureneedles.net";
$dot_net_url="indexx.htm";
$dot_com_url="flash";
if(($HTTP_HOST=="$domain_net")or($HTTP_HOST=="www.$domain_net"))
{
Header("Location: $dot_net_url");
}
else
{
Header("Location: $dot_com_url");
}
?>

$domain_net="sutureneedles.net";
$dot_net_url="surgicalneedle/";
$dot_com_url="flash";
if(($HTTP_HOST=="$domain_net")or($HTTP_HOST=="www.$domain_net"))
{
Header("Location: $dot_net_url");
}
else
{
Header("Location: $dot_com_url");
}
?>

如有端口，还要加上端口号，如端口号为81：

$domain_net="sutureneedles.net";
$dot_net_url="surgicalneedle/";
$dot_com_url="flash";
if(($HTTP_HOST=="$domain_net")or($HTTP_HOST=="www.$domain_net:81")or($HTTP_HOST=="www.$domain_net")or($HTTP_HOST=="$domain_net:81"))
{
Header("Location: $dot_net_url");
}
else
{
Header("Location: $dot_com_url");
}
?>
