Output generated html code before end of script execution

[eluser]jant90[/eluser]
Is it possible to output the so far generated html code with CodeIgniter? When I load a slow script now I don't see anything in my browser until the script is completely done.

For example take the default controller:

Code:

function index()
{
    $this->load->view('welcome_message');
    
    // Code to output all the html generated above
    
    sleep(10);
    echo("script is done loading");
}

How do I make sure my browser already gets to see the welcome message before the 10 second sleep kicks in?

Is it even possible?
