[Catalyst] Please Help: Aborting a Catalyst request in auto method

It looks okay actually, documentation:

"If an |auto| action returns 0, any remaining actions will be skipped, 
except for |end|".

It goes directly to end. You should restructure your code probably, so 
that the main handling doesn't happen in end. You can also use detach if 
you want. Also you may want to use the existing plugins for Authentication.
