Cronjob via HTTP

@Silentium:
Yes, this is what I know already, but I tested it once with http and with the file method. The file method gave me an error right away, because /path/to/index.php cronjobs update is not a file.

For the http request I created this method in the cronjobs Controller:

PHP Code:

   public function update_news_until_data()
    {
        if($this->input->is_cli_request() === TRUE)
            echo 'cronjob ausgeführt';
        else
            echo 'kein cli request';
    } 


when executing it through the cronjob (yeah, I can directly execute it via the interface) i get 'kein cli request' = no cli request.

Or did I get you wrong?

@CroNiX:
Hm.. the key could be a possibility, but I think I will wait for some more feedback, but I keep this in mind.

For the other answer.. I don't think it will do some difference, because my webhost can execute cronjobs via http and make them in a interval. The problem is, that everyone else who knows the controller/method, can execute it, and this is something i don't want.
