Dynamic Data Updates
HAProxy Enterprise's Update module allows you to update the contents of ACL files, Map files, and TLS ticket key files periodically without reloading HAProxy Enterprise. At startup, the process loads the contents of the files. Then, at a set interval, it downloads updates to the files from a specified URL. The content of the downloaded file(s) replaces the existing content.
This mechanism allows you to keep ACL and Map files up to date on multiple instances of HAProxy Enterprise. Each instance will check for changes independently.
