Hi Daniel, Something not clear in your request is that do you want to route ALL traffic after an error, or only the traffic from a single user? You may use the 'stick store-response' when an error is returned by the server and track it when traffic comes in with the in_table fetch. This may require you to switch to HAProxy 1.6-dev. Baptiste
