base_url Link Issue

Question

I'm using following code:

$config['base_url'] = "http://www.aaa.com/";

Also Im using Flash navigation:

on(release) {
getURL("http://www.aaa.com/xxx/index");
}

The Problem is When I give url as http://aaa.com in address bar Flash navigation link is not working. If i give link from http://www.aaa.com its work perfectly.

Can anyone solve my issue?

Or else, is it possible to use like this:

$config['base_url'] = "http://www.aaa.com/";
$config['base_url'] = "http://aaa.com/";

This question is quite vague. But to redirect to www using .htaccess try:

RewriteCond %{HTTP_HOST} !^www|localhost
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [L,R=301]
