@Deprecated
public abstract class ServerConnectionHelper
extends ConnectionHelper<Server>

Base server helper based on NIO non blocking sockets. Here is the list of parameters that are supported. They should be set in the Server's context before it is started:

Parameter name	Value type	Default value	Description
useForwardedForHeader	boolean	false	Lookup the "X-Forwarded-For" header supported by popular proxies and caches and uses it to populate the Request.getClientAddresses() method result. This information is only safe for intermediary components within your local network. Other addresses could easily be changed by setting a fake header and should not be trusted for serious security checks.
reuseAddress	boolean	true	Enable/disable the SO_REUSEADDR socket option. See java.io.ServerSocket#reuseAddress property for additional details.
