Denis,

Possible and fairly straightforward.

First, get the server name $_SERVER['SERVERNAME']
test it to determine if it is one to be protected,
then you have a choice.
you can use PHP_Authentication to send a challenge screen,
or you can send a login screen then you need to validate against a database
or a text file or a constant within the script itself.

the PHP manual covers the authentication test but beware that the
documentation was written with register_globals on so you need to handle
the variables as subscripts to the appropriate superglobals array if
register globals is off

Hm, you could maybe try something like:

<?
$allowed_servers = array(
'server1',
'server2',
'server3',
'server4');

if (!in_array($_SERVER['SERVER_NAME'], $allowed_server)) {
die("Server not allowed.");
}
... // Your code
?>
