HAProxy is a free and open-source load balancer that enables IT professionals to distribute TCP-based traffic across many backend servers. In this book, the reader will learn how to configure and leverage HAProxy for tasks that include:

  • Setting up reverse proxies and load-balancing backend servers
  • Choosing the appropriate load-balancing algorithm
  • Matching requests against ACLs so that we can route them to the correct servers
  • Monitoring servers with health checks so that failure is detected early
  • Managing server persistence so that a client's can be directed to the server where their session data is stored
  • Configuring verbose logging for TCP and HTTP-based services
  • Enabling SSL encryption, gzip compression and geolocation
  • Modifying HTTP headers, rewriting URLs and setting up redirects
  • Defending against malicious Web activity
  • Controlling HAProxy from the command line
  • Adding a backup load balancer
