ProxyHandler

public abstract class ProxyHandler extends Object
Abstract class allowing a backend appserver instance to retrieve information about the original client request that was intercepted by an SSL terminating proxy server (e.g., load balancer).

An implementation of this abstract class inspects a given request for the custom request headers through which the proxy server communicates the information about the original client request to the appserver instance, and makes this information available to the appserver.

This allows the appserver to work with any number of 3rd party SSL offloader implementations configured on the front-end web server, for which a corresponding ProxyHandler implementation has been configured on the backend appserver.
