Hi Uri,

you're wrong.
"t_on_branch" works before the request is sent out....
The branches work in the manner, you program them in your logic (e.g.
set the timeout for a request, then use failure route for serial
branches). There is no general switch (and i'm not aware of any good
docs regarding this) in order to do serial or parallel branches.
