i have the same situation in my one of my controls: some of functions
should work for both auth and non auth people. For this control i
have misc:is_auth(soft,SessionID). which returns {ok,{not_found}}; in case
user was not found and then i ignore response with help of pattern
matching. For controls which are for auth users only i
use misc:is_auth(hard,SessionID). which makes redirect in case of non auth
user.
