Thanks Greg
That works OK.
I have another problem: i have two back ends 1 'tester' inserts tasks
to a queue with 'PULL' method.
and another 'worker' that leases the tasks and process them. the
'tester' backend works fine.
the 'worker' I get an exception at lease_tasks function
the stack is as follows:
[Remote API Server] [handler.py:308] ERROR Exception while handling
service_name: "taskqueue"
