All Implemented Interfaces:

ChannelHandler

public class SniHandler
extends ByteToMessageDecoder

Enables SNI (Server Name Indication) extension for server side SSL. For clients support SNI, the server could have multiple host name bound on a single IP. The client will send host name in the handshake data so server could decide which certificate to choose for the host name.
