Path to application, cache or logs

[eluser]Maximilian Schoening[/eluser]
Hi,
do I need to specify the full path to the applications, cacher and logs folder or can I do something like this aswell:

Code:

$application_folder = "../application/";

$config['log_path'] = '../data/logs/';

$config['cache_path'] = '../data/cache/';

Thanks,
Max
