A brief introduction to the principle1.HAProxyHaproxy provides high availability, load balancing, and proxies based on TCP and HTTP applications, supporting virtual hosting, which is a free, fast, and reliable solution. Haproxy is especially useful for Web sites that are heavily loaded, and often require session-hold or seven-tier processing. Haproxy runs on today's hardware and can support tens of thousand
