## 8.3. Configuring the Web Server and Load Balancer

The front-end web server communicates with the application server(s) on the EKM cluster node(s) using the mod_proxy load balancer. This load balancer forwards requests from the web server to the application server(s) (Figure 8.1: Communication for EKM with Front-End Web Server). In a multi-node EKM server, mod_proxy also provides load balancing of client connections to the cluster nodes. mod_proxy handles the communications between the front-end web server and application server(s). mod_proxy can be configured to use HTTP, or HTTPS.

This chapter provides instructions for configuring mod_proxy for use with HTTP. To configure mod_proxy for use with HTTPS, please consult the mod_proxy documentation. Note that the communications between the client and the front-end webserver are not impacted by the choice of communication protocol for mod_proxy. For example, a client such as a web browser may communicate with the front-end web server using HTTPS, while the front-end web server (via mod_proxy) communicates with the application server(s) on the EKM cluster node(s) using another protocol such as HTTP.
