To turn a connection between a client and server from HTTP/1.1 into WebSocket, the protocol switch mechanism available in HTTP/1.1 is used. There is one subtlety however: since the “Upgrade” is a hop-by-hop header, it is not passed from a client to proxied server. With forward proxying...
通过PROXY协议,NGINX和NGINX Plus可以接收通过代理服务器和负载均衡器(例如HAproxy和Amazon Elastic Load Balancer(ELB))传递的客户端连接信息。 使用PROXY协议,NGINX可以从HTTP,SSL,HTTP / 2,SPDY,WebSocket和TCP学习原始IP地址。了解客户端的原始IP地址对于设置网站的特定语言,保留IP地址黑名单或仅用于日志记录和统计目...

proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; 升级http1.1到 websocket协议。另外有一个特别值得注意的地方是,如果websocket服务器在收到websocket握手包,查看Origin信息与所在域信息不符的话。会直接拒绝服务。这点很坑,我花了接近半天的时间来找为什么连...
被用来升级连接从HTTP到WebSocket的HTTP Upgrade机制使用Upgrade和Connection头部来完成。在反向代理服务器支持WebSocket中,需要面临一些挑战。第一个是WebSocket是一个hop-by-hop协议,所以当代理服务器拦截来至于客服端的一个Upgrade请求时,代理服务器需要发送它自己的Upgrade请求给后端服务器,包括一些合适的头部。同样,因为...

WebSocket connections are failing on me. :( My scenario is the common case of HTTPS with a HTTP upstream. Browser sends requests with "wss:" protocol and gets a 400 error code. I did mess around with the template, but I don't think I bro...
WebSocket 是一种基于TCP连接的全双工通信的协议,其工作在应用层,建立连接的时候通过复用 Http 握手通道,完成 Http 协议的切换升级,即切换到 WebSocket 协议,协议切换成功后,将不再需要客户端发起请求,服务端就可以直接主动向客户端发送数据,实现双向通信。
