Hi, Alexks, I try your proposal and it doesn't work. Actually my issue is the same as this one http://stackoverflow.com/questions/5100971/nginx-and-proxy-pass-send-connection-close-headers. 1. I add "keeplive_request 0". The result is that the "Connection: close" header is sent to client for e

Hi, Aleks, Actually I read what you mention. The document about "proxy_pass_header" just pass the headers listed in "proxy_hide_header" which do not include "Connection", so I think it might doesn't work. I will try this. BTW, this module ngx_http_upstream_module should be built by default righ

回复：Re:_回复：Re:_Issue_about_nginx_removing_the_header_"Connection"_in_HTTP_response?

Hi, Alexks, I don't want to hide the header. My problem is that Nginx change the "Connection: close" header in the reponse from upstream server to "Connction: keep-alive" and send to client. I want to keep the original "Connection: close" header. Thanks Liu Peng - 原始邮件 - 发件人：Aleksandar

Issue about nginx removing the header "Connection" in HTTP response?

Hi, nginx guy, In our system, for some special requests, the upstream server will return a response which the header includes "Connection: Close". According to HTTP protocol, "Connection" is one-hop header. So, nginx will remove this header and the client can't do the business logic correctly

回复：Re: why "connection: close" header is added when the request is passed to upstream server?

Hi, Maxim, You are right. Connection is hop-by-hop header. At present I add the line below into nginx.conf: proxy-set-headers Connection $http_connection That solve my issue. Thanks Liu Peng - 原始邮件 - 发件人：Maxim Dounin 收件人：nginx@nginx.org 主题：Re: why "connection: close" header is added w

why "connection: close" header is added when the request is passed to upstream server?

Hi, Nginx guy, I use Nginx in the Kubernetes. With the upstream server log, I find that the header "connection: close" is added when the request is passed to upstream server. Why? What I hope is the original header relating to connection status should be passed to upstream server without any

回复：Re: Can nginx has the capability to dynamically limit the connections when the upstream server has full load

Hi, Bartenev, Our backend server is an old product existing for more than 20 years. When a client login in to the backend server, a session is created. The session will be terminated when the client log out. To prevent the server from out of memory issue, we can configure the max allowed sessio

Can nginx has the capability to dynamically limit the connections when the upstream server has full load

Hi, I have a scenario: my backend servers provide URL to query whether this sever can accept new connections (the http response body is "true" or "false"). This server also has configuration for the max allowed session. Now I want to use Nginx as load balancer. Does Nginx provide such kind of
