Well, I'm sure CI doesn't include this rule because everyone will have their own idea of what to allow as a url. Like, do you allow underscores, capital letters, etc. Personally I only allow lower-case letters, numbers and dashes.
Its easy to make your own validation rule(s) for your url case and extend Form_validation.
Heres a rule for only lower-case letters, numbers, and dashes
Code:
function valid_url($str)
{
$this->set_message('valid_url', 'The %s field may only contain lower-case letters, numbers, and dashes.');
return ( ! preg_match("/^([a-z0-9-'])+$/", $str)) ? FALSE : TRUE;
