Hi Guys

Before a month I got a script for page redirection from somewhere in the forums.

var pAddy = self.location.href;
var pHost = self.location.hostname;
var pPath = self.location.pathname;
var nuLoc = 'http:/' + '/www.' + pHost + pPath;
if(pHost.indexOf('www.') == -1) self.location.replace(nuLoc);

save this file on server name it, suppose abc.js

Then call this .js page to home page of your website
<SCRIPT language="JavaScript" src="abc.js"> </SCRIPT>

It really works.

Now I would like to know, does it effect my website in one or other way. If anybody knows about this script and its cons please reply this post.

It certainly could

everypage beyond the one with the redirect script is invisible to the SE spiders.

yea JS redirection is not good, because it only redirects javascript enabvled users, and wont redirect spiders. I would recommend a server side redirection script. But then there might be problems with XSS hacking, so you should input check for that. I do not know how to do this type of attack, and i don't know if it would apply to the bottom script. Bujt just to be sure:

Possibly in PHP something like:
<?php
ob_start();
$_GET = Array(); // security
header("Location: http://www.designplanet.biz");
ob_end_flush();
?>

Javascript redirects are seen by google as sneaky and generally construed as blackhat. Use a proper 301 to redirect where you need.
