December 10, 2015 05:21AM
i am using nginx as a reverse proxy server(Let 's call it Server A). server A's upstream server is also a nginx server((Let 's call it Server B) backend with a jetty server((Let 's call it Server C) served at port 8080. we have a lot of Server A and each one of them use the same bunch of server B as upstream, each server B use its local jetty server as its own upstream server. server A and Server B work at port 80.

i found few http response code 498 from server B about 2 or 3 days ago . google on it found little information ,any one has some idea ?

server A config:

location /views/3.0/ {

if ( $query_string ~* ^(.*)req_times=[2-3](.*)$ ){
return 444;
}
proxy_pass http://views_java_sec_cnc;
proxy_set_header REMOTE_ADDR $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

proxy_next_upstream http_500 http_502 http_504;
limit_req zone=java burst=5 nodelay;
proxy_next_upstream_tries 1;

}

Server B config:

# views
location /views/ {
proxy_pass http://views_server;
proxy_redirect off;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Real-IP $remote_addr;
proxy_http_version 1.1;
proxy_set_header Connection "";
#proxy_pass_request_body off;
#proxy_cache IFACE;
limit_req zone=views-java burst=5 nodelay;
}
