The existing code does resubmit the body if the enable_redirect is set
statically or set early enough in the life cycle of the transaction. This
change adjust the logic to enable the body resubmit if the decision is made
later. This was a customer request. We may want to reconsider our decision to
redirect posts, but I think that is a different bug than this one.
