I don't think balance hdr(host) is the correct load-balancing method then. > Is there a way to redispatch the requests to other servers ignoring the > persistence on queue timeout? No; after a queue timeout (configurable by "timeout queue"), haproxy will drop the request. Think of what would happen when we redispatch on queue timeout: The request would wait seconds for a free slot on the backend and only then be redispatched to another server. This would delay many requests and hide the problem from you, while your customers furiously switch to a competitor. You should find another way to better distribute the load across your backends.
