Class AbstractSniHandler<T>

java.lang.Object

io.netty.channel.ChannelHandlerAdapter

io.netty.channel.ChannelInboundHandlerAdapter

io.netty.handler.codec.ByteToMessageDecoder

io.netty.handler.ssl.AbstractSniHandler<T>

All Implemented Interfaces:

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

Direct Known Subclasses:

SniHandler

public abstract class AbstractSniHandler<T>
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.
