HAProxy Enterprise Documentation 1.6r2

Dynamic-update

The dynamic-update section lets HAProxy Enterprise pull updated ACL and Map files from a remote server. This allows a cluster of HAProxy Enterprise instances to stay in sync.

After the Update module is installed, we can list one or more update lines in a dynamic-update section. Each specifies a file to pull from a remote server to the current load balancer instance.

global

dynamic-update
   update id /etc/hapee-1.6/redirects.map url http://10.0.0.1:80/redirects.map  delay 5m  timeout 5s  retries 3  map  log  dontlog-normal
