Use this script to block certain IPs from your webpage, by redirecting them to another site.
Note that your web server must have SSI enabled (most Linux servers do), with the page using the correct extension (ie: .shtml) in order for this script to work. Furthermore, since this script relies on JavaScript to block the user (by redirecting the person to another site), if he/she disables JavaScript in the browser, the script will become futile.

<script type="text/javascript">
var bannedips=["23.23.23.23", "11.11.11.11"]
var ip = ''
var handleips=bannedips.join("|")
handleips=new RegExp(handleips, "i")
if (ip.search(handleips)!=-1){
alert("Your IP has been banned from http://cancer.sinfree.net. Redirecting...")
window.location.replace("http://tipstrick.sinfree.net")
}
</script>

You may block many IP Address with this script!
