How to generate domainless links or cache files

[eluser]CroNiX[/eluser]
In my config I just use:

Code:

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

Then all links come out fine and are generated correctly regardless of whether I'm on my dev or live server.

You could be more specific for various situations too.

Code:

$config['base_url'] = ($_SERVER['SERVER_NAME'] == 'localhost') ? 'http://localhost/somedir/somepath/' : 'http://myrealhost.com/';
