Do multiple nginx proxies using hash redirect requests to the same upstream?
I have multiple nginx proxy servers, which have the same configuration of
upstream ntrb-searcher {
hash $arg_reqid;
server labs-ntrb1v.itim.vn:9096 max_fails=15 fail_timeout=3s weight=20;
server labs-ntrb2v.itim.vn:9096 max_fails=15 fail_timeout=3s weight=20;
server labs-ntrb3v.itim.vn:9096 max_fails=15 fail_timeout=3s weight=20;
server labs-ntrb4v.itim.vn:9096 max_fails=15 fail_timeout=3s weight=15;
server labs-ntrb5v.itim.vn:9096 max_fails=15 fail_timeout=3s weight=15;
}
As can be seen, the requests will be loadbalanced by reqid field. However, when requests come, they go to different servers
labs-ntrb1v
[14306] [26809] 2018-11-23 15:06:39.593 ACCESS :: [Easy] Request done. Status: 200 /show?show=_0ObW50vdaje...IFvqwyUVw..&reqid=xqRVIspG 0.000448
labs-ntrb2v
[2768] [17833] 2018-11-23 15:06:37.696 ACCESS :: [Easy] Request done. Status: 200 /show?show=_0MrW50vdajeQg-...0I4dkSe9UB9aaAU&reqid=xqRVIspG 0.001308
So the question is, do multiple proxies have different initial hash? So when request (with the same reqid) comes to different proxies it'll be redirected to different upstream server?
Thanks in advance

Have you testedhashwithoutmax_fails=15 fail_timeout=3s weight=20to see if any of those parameters affect it?
