hi, currently i use nginx to handle a configuration, but i'm unable to do there what i need, so i'm looking into haproxy, if i could use it for load-balancing.
what i'd like to achieve is: - i have mutliple backends (let's say 2: backend-a, backend-b) - when a request comes in, i want it to be proxied round-robin to one of the 2 backends - let's say it is sent to backend-a - now, if backend-a is unavailable (the port is closed for example), or, it's socket-backlog is full, i want haproxy to try backend-b - haproxy should not try backend-b in any other case. for example, if backend-a already started to read the request, and then crashed, backend-b should not be tried. an error should be sent to the client. basically i want to be able to failover when the socket-backlog is full, but i do not want to double-process any http-requests. is this possible with haproxy? thanks, gabor
