Problem redirecting to an html page outside my application

[eluser]Jay Turley[/eluser]
In my root, there are two files:

index.html // the site index page
application.php // the CI controller for dynamic portion of site

After performing certain tasks, I wish to redirect to index.html

Obviously, using

Code:

$this->load->helper('url');
redirect('index.html');

would be a FAIL.

Not being very familiar with PHP yet, I tried

Code:

http_redirect('/index.html');

This did not work.

Can anyone out there point me toward the proper way to do this?

Thanks a ton!
