Run only if calling script on same server

echo

Hi,
Have done a search but perhaps I don't know the correct terms to use.
I need for script A to check that script B (which is getting a value from it) is on the same server. Script A is a Flash file and script B php, so I don't what anyone to be able to get the value returned by the php file by typing in the URL.
Sorry if that's as clear as mud 🙂
Thanks for any assistance.
Martin

if(strstr($SERVER_NAME,$HTTP_REFERER)) {
// call script b
} else {
echo "You do not have permission call script b from $HTTP_REFERER";
}

echo

Thanks for the tip but alas the referer variable doesn't seem to be set. Perhaps it's a Flash thing because I've tried calling phpinfo from flash and it doesn't show the referer.
Any other ideas (please)?

If I'm not mistaken, REFERER is passed in through the incoming headers. So maybe your Flash script isn't handing any out. If this is the case, then maybe you could try testing for $HTTP_REFERER, and if it is present, test again to see that it is your server. Otherwise, deny permission. ie:

function checkReferer()
{
    if(strstr($SERVER_NAME, $HTTP_REFERER))
    return true;
}

if ($HTTP_REFERRER && checkReferrer())
    echo "This is a polite message to you: you can't use my script without permission!";
else
    echo "Do your stuff, because it's probably coming from your own server.";

Hope that was useful ...

Once again I thank you for your help but it seems that HTTP_REFERER is not set. I'm going right off Flash😃
