base_url Link Issue

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:开发者_JS百科//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]

Is the flash object trying to read a page / data from the server? In this case, Cross-domain policy for flash prevents form accessing data which resides on other domains. (Sub domains, such ass www.aaa.com and aaa.com are treated as different domains.) You would need to add a crosdomain.xml policy file http://kb2.adobe.com/cps/142/tn_14213.html

If Petah's answer doesn't help you, then it could very well be a setting with your web server. I use shared hosting and I know whenever I configure a new domain I have an option like this:

If you own your own web server, check the httpd.conf file. Otherwise, if it's on shared hosting, see if there's a setting for making it required/non-required.
