[SECURITY] Fedora 29 Update: mod_cluster-1.3.11-1.fc29

Mod_cluster is an httpd-based load balancer. Like mod_jk and mod_proxy, mod_cluster uses a communication channel to forward requests from httpd to one of a set of application server nodes. Unlike mod_jk and mod_proxy, mod_clus ter leverages an additional connection between the application server nodes and httpd. The application server nodes use this connection to transmit server- side load balance factors and lifecycle events back to httpd via a custom set of HTTP methods, affectionately called the Mod-Cluster Management Protocol (MC MP). This additional feedback channel allows mod_cluster to offer a level of intelligence and granularity not found in other load balancing solutions.
