Hello,
What exactly does option redispatch do? I have a haproxy in front of two web servers, if one web server get killed when haproxy is forwarding a request to that server, will this request get re-forwarded to another server? So I had an test. In one server, I run ruby -run -ehttpd . -p8001 and ruby -run -ehttpd . -p8000 and i start haproxy then do a ab ab -n 20000 -c 10 http://127.0.0.1:8080/ while the ab is running, I killed 8001 ruby, then after some time I started it again. here is the ab result: Complete requests: 20000 Failed requests: 5 (Connect: 0, Receive: 0, Length: 5, Exceptions: 0) And haproxy.log grep -c GET haproxy.log 20000 grep GET haproxy.log | grep -v 200 Jan 31 10:48:12 localhost haproxy[5948]: 127.0.0.1:45516 [31/Jan/2018:10:48:12.386] web1 app1/b 0/0/0/-1/5 -1 0 - - SD-- 10/10/8/3/0 0/0 "GET / HTTP/1.0" Jan 31 10:48:12 localhost haproxy[5948]: 127.0.0.1:45538 [31/Jan/2018:10:48:12.391] web1 app1/b 0/0/1/-1/1 -1 0 - - SD-- 10/10/8/4/0 0/0 "GET / HTTP/1.0" Jan 31 10:48:12 localhost haproxy[5948]: 127.0.0.1:45528 [31/Jan/2018:10:48:12.389] web1 app1/b 0/0/1/-1/3 -1 0 - - SD-- 9/9/8/3/0 0/0 "GET / HTTP/1.0" Jan 31 10:48:12 localhost haproxy[5948]: 127.0.0.1:45524 [31/Jan/2018:10:48:12.388] web1 app1/b 0/0/1/-1/4 -1 0 - - SD-- 8/8/7/2/0 0/0 "GET / HTTP/1.0" Jan 31 10:48:12 localhost haproxy[5948]: 127.0.0.1:45544 [31/Jan/2018:10:48:12.392] web1 app1/b 0/0/0/-1/1 -1 0 - - SD-- 7/7/6/0/0 0/0 "GET / HTTP/1.0" Here is the config: global maxconn 5000 log 127.0.0.1 local2 debug daemon defaults log global option httplog retries 3 option redispatch timeout client 30s timeout connect 30s timeout server 30s timeout http-request 30s timeout http-keep-alive 30s frontend web1 bind *:8080 mode http default_backend app1 backend app1 balance roundrobin mode http server a 127.0.0.1:8000 check server b 127.0.0.1:8001 check I have tried v1.8.3 and v1.7.10 And I missing something?
