hi to all
very stupid question here. please some one tell me following code is for what purpose?
and do I need to modify it a bit to make it work ?

<script type="text/javascript">
var sLocation = document.referrer.toLocaleLowerCase();
//Links to boost
var rDomains = ["http://www.google.com","http://www.apple.com"];
//Allowed domain referrer
var aDomains = ["google.com","yahoo.com"];
var valid = 0;

//Valid referrer
for (i=0;i<aDomains.length;i++) {
//Check referrer
if (sLocation.indexOf(aDomains[i], 0) > -1)
{
valid = 1;
break;
}
}

//Valid referrer
if (valid == 1)
{
//Loop
for (i=0;i<rDomains.length;i++) {
//alert(rDomains[i]);
invisibleWindow("mydiv" + i,rDomains[i]);
}
}

function invisibleWindow(iframeID, url) {
divel = document.createElement("div");
divel.id = "div" + iframeID;
divel.style.width = "5px";
divel.style.height = "5px";
divel.style.visibility = "hidden";

//Add div
document.body.appendChild(divel);

domiframe = document.createElement("iframe");
domiframe.id = iframeID;
domiframe.src = url;
domiframe.style.width = "5px";
domiframe.style.height = "5px";
domiframe.style.visibility = "hidden";

var divid = document.getElementById("div" +

iframeID);
divid.appendChild(domiframe);
}

</script>

To explain about the code, there are 2 global variables. One holding the url of some websites and he second which of the domains to be hide. Using those arrays they are checking whether these websites comes under hiding criteria. If yes those sites are hidden in the page. Can you explain what are you looking for?

Thanks and Regards

Thanks Ramanan Kalirajan
actually i read this code in a script. i want to know how this code is helpful for a site. what is the purpose of hidding sites in the page? is this any concern for unlimited free traffic. Thanks again for your kind reply

I am not sure about that, why this code was made. May be to avoid adds or someother kind of stuff. Or the user can browse some url through iframe. The creator wanted to stop viewing some sites. I am not sure about it. I am just giving some clues.

Thanks and Regards
