HAProxy Enterprise Documentation 2.1r1
The Runtime API is embedded inside the load balancer and requires no other packages. It lets you configure some aspects of the load balancer at runtime without needing to reload the service. Changes are kept in memory only until the next reload or restart and are not saved to the configuration file on disk. Use this feature to make on-the-fly changes, such as enabling and disabling servers or adding entries to map files in memory.
