Finished working on my class to serve static content to users using 3 different servers, so here's the script, for those who will know how to implement it xD

Summery: Basically what this does is you can use several different hosts, for one thing. This optimizes your server for a faster experience for your users/clients

PHP Code:
<?php
    
class ZapDataNetwork
    
{
        
// Function to check if a cdn is offline. Use IP or http:// method for fsockopen as $link.
        
public function CDNOnline($link)
        {
            if(@
fsockopen($link80$errno$errstr1)) // Check if the connection fails
            
{
                return 
true// Connection suceeded
            
}
            return 
false// Connection failed
        
}
        
        
// Function to serve a CDN to each user
        
public function AssignCDN()
        {            
            
$this->cdn['1'] = ""// Force Hotel & Open Habbo CDN
            
$this->cdn['2'] = ""// Habless Hotel CDN
            
$this->cdn['3'] = ""// Zap Hotel CDN
            
            
$this->result rand(13);
            
            
// Lets check if the servers are online, and assign a server for users as they show up.
            
if($this->result == '1' && !$this->CDNOnline($this->cdn['1']))
            {
                
$this->result '2';
            }
            else if(
$this->result == '2' && !$this->CDNOnline($this->cdn['2']))
            {
                
$this->result '3';
            }
            else if(
$this->result == '3' && !$this->CDNOnline($this->cdn['3']))
            {
                
$this->result '1';
            }
            
            
// Return the CDN for the user
            
return 'cdn' $this->result '.zaphotel.net';
            
        }        
    }
    
?>
Basically all this does is randomise the webserver that the user gets to get the content. If you go to zap you will get a random between cdn1 or cdn2 or cdn3 to serve images and SWFs to load balance.

Have fun & enjoy coding!
