[Pdns-users] pipe backend

[Sean Leach]

Figured it out.  The backend.pl needs \t in place of the spaces in  
the response.  When I copied from the webpage (or copied the  
backend.pl via copy/paste instead of cp), it had tab characters and  
vim expanded it to spaces (as it should), so it was user error :)  It  
needed tabs.
