Class SniHandler

java.lang.Object

io.netty.channel.ChannelHandlerAdapter

io.netty.channel.ChannelInboundHandlerAdapter

io.netty.handler.codec.ByteToMessageDecoder

io.netty.handler.ssl.SniHandler

All Implemented Interfaces:

io.netty.channel.ChannelHandler, io.netty.channel.ChannelInboundHandler, io.netty.channel.ChannelOutboundHandler

public class SniHandler
extends io.netty.handler.codec.ByteToMessageDecoder
implements io.netty.channel.ChannelOutboundHandler

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.
