includes some other php file, (lets call it test.php) then in test.php,
you could test $_SERVER['PHP_SELF'] == '/index.php'. and if that fails,
you know someone is attempting to use test.php directly. if it passes,
you know it is from your index.php.

for example, your index.php would have something like this:

<?php
include_once('test.php');
?>


and then test.php would have something like this:

<?php
if($_SERVER['PHP_SELF'] != '/index.php')
{
die(' you leach!!!');
}
else
{
echo 'very good';
}

?>


try that out and let me know if that is what you are looking for.

accessible from within your site (after logging in, for example), use a
session. In the session, you can set a variable that says a user is
logged in or a visitor has come through the site home page. This is not
restricted to html content, images can be created or sent from PHP as well.

Best regards

re: Anti Leech php script

Sorry
May be I'not so good at explanig things
But I think with a help of James I can already do something

It's simple
On may page I have a collection of external links (ex. cnn.com,
bbc.com and etc)
I would link to change my HTML links and to point not directly to
these sites but (now I think it's clear) with a check of the request
on the server.
By the way how open the link in a browser if all is ok?
I mean the user click a link, a part of PHP code checks on the server
and what after?
How to open it in a browser?

Sorry I'dont know much in PHP

Thakns to all of you

allows you to present an external web page within a frame of your web
page. So the user never leaves your web site.

Here are some links that descript the <iframetag.

A pretty standard way to check 'outside links'.
Use a GET variable (post is possible, but unneccesary work) to a
redirection script, either hashed, plain, encrypted or unecncrypted,
whatever you like. In the redirection script, save everything from the
$_SERVER array you're interested in, and do the actual redirect by a
header redirect.

all about HTTP and HTML.

It more commonly arises in discussions on CSRF (Cross Site Request
