haproxy windows

Haproxy is a free and open source software written in C that provides high availability, load balancing, and TCP and HTTP-based application proxies that can run on most major Linux operating systems.This experiment uses three servers to build a Web cluster, haproxy as a dispatch server, two Nginx servers as node servers.Experimental environmentHost | System | IP Address | As long as the software

HAProxy introduction, haproxySimple Description HAProxy provides high availability, Server Load balancer, and TCP and HTTP application-based proxy. It supports Virtual Hosts and is a free, fast, and reliable solution. HAProxy is especially suitable for websites with extremely high loads, which usually require session persistence or layer-7 processing.

not go out from itself, this ensures that the performance of the Equalizer IO will not receive large traffic impact.5, the application of a wide range, because LVS work in the 4 layer, so it can almost all applications to do load balancing, including HTTP, database, online chat room and so on.The disadvantages of LVS are:1, the software itself does not support regular expression processing, can not do static and dynamic separation , and now many sites in this area have a strong demand, this is

Hide back-end server versionsIn our daily work we use haproxy as a load balancer, because the backend application server is more cumbersome to change, so it is decided to implement it in the load balancer.Only need to frondend or listen or backend, addRspidel ^server:.* rspidel ^x-forwarded-for:.* rspidel ^x-powered-by:.* rspidel ^via:.* rspide L ^x-aspnet-version:*The above use can refer to Rspidel.In addition, if you need to confuse some people t
