[quote author="[CoDeR]" date="1209063588"]I do not know why CI doesn't adopt this method but i ALWAYS change my base_url to this:

Code:

$config['base_url'] = "http://".$_SERVER['HTTP_HOST']."/";

you could always do more work on it, like detecting the protocol.[/quote]

Unfiltered server vars?

Code:

$this->input->server();
