I'm just new to openser, and this list. I implemented a load balance server, but I'm getting some trouble with this 473 response from openser. I inserted a fake uri to test how the load balance server would handle the problem. Ok, it tries to send the request, fails, and then goes to the failure route. There, it goes to the next route. Next time the server tries to send the request to the fake uri, I'm getting the 473 response. Yes, the fake uri is black listed. But how should we be able to treat this error? Instead of immediatly returning this message to the UA, I'd like openser to go to the next uri found in the list. I'd prefer not to disable the blacklist function. I saw that other people had the same problem, but I couldn't find any final solution. Am I missing something or is it a bug? I'm posting my code just below.
