PHP - Only That Referer !

I have htaccess file from which I am calling htpasswd.
Currently its ask for authentication from everyone.

I want it IP based or Domain based so that a user requesting from specific IP may not have to go through http authentication.

Some domain calling the web pages in background like paypal OR  google checkout can access the page without http authentication.

Is it possible ?

content of htaccess file is given below.

AuthUserFile /var/www/web/.htpasswd
AuthName "Authorization Required"
AuthType Basic
<Limit GET POST>
   require user username
</Limit>

Im working on an issue that keeps sending the user to logge_in.php and never to post_new.php even if it is the referer. Here is the code I have wrote so far:

Code: [Select]

if($_SERVER['HTTP_REFERER'] =="post_new.php"){
 $referer = "post_new.php";
}elseif($_SERVER['HTTP_REFERER'] =="logged_in.php"){
 $referer = "logged_in.php";
}

header("Location: ".$referer." ");
exit();
}


Thanks in advance!

I need to close a window if referer not valid, but it cannot be in HTML, needs to be php. This is what I have so far:

Code: [Select]
if (ereg("http://www.mysite.com/test.php", $_SERVER['HTTP_REFERER']) != true){
header('Location: ?????????');
exit;
} I get a header already sent message if I use a URL. I need it to close the window after 3 seconds.

Any ideas?

Hoping someone can help.

I have a file, say bounce.php that uses php url ramdomizer, like this:

<?php
$urls = array("link1",
                      "link2");
$url = $urls[array_rand($urls)];
header("Location: http://$url");
?> 

What I want is to only allow that code to execute if the user is coming from another php page on the same sever/folder.  So like this....

So bounce.php will check where the traffic is coming from.....if traffic is coming from page1.php (file on same server) then it will allow URL REDIRECT CODE to execute, if traffic is coming from another source, such as google.com, or from no referel, then person is sent to another site, say msn.com.

now i use this code to show where the visitors came from to my site.

<?php
$referer=$_SERVER['HTTP_REFERER'];
echo $referer;
?>

now, i want to show the  5 latest vistors referer's site url on my site ?
