    Name        : mod_cluster
    Product     : Fedora 29
    Version     : 1.3.11
    Release     : 1.fc29
    URL         : https://modcluster.io/
    Summary     : Apache HTTP Server dynamic load balancer with Wildfly and Tomcat libraries
    Description :
    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_cluster
    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 (MCMP).
    This additional feedback channel allows mod_cluster to offer a level of
    intelligence and granularity not found in other load balancing solutions.
