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;
}

```

498 is not something nginx returns unless explicitly configured to  
do so. Unless you see something like “return 498” in your nginx  
configs, try looking into your backend server code instead.
