Package io.netty.handler.codec.http

Class HttpServerExpectContinueHandler

java.lang.Object

io.netty.channel.ChannelHandlerAdapter

io.netty.channel.ChannelInboundHandlerAdapter

io.netty.handler.codec.http.HttpServerExpectContinueHandler

All Implemented Interfaces:

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

public class HttpServerExpectContinueHandler
extends io.netty.channel.ChannelInboundHandlerAdapter

Sends a 100 CONTINUE HttpResponse to HttpRequests which contain a 'expect: 100-continue' header. It should only be used for applications which do not install the HttpObjectAggregator.

By default it accepts all expectations.

Since HttpServerExpectContinueHandler expects HttpRequests it should be added after HttpServerCodec but before any other handlers that might send a HttpResponse.

  ChannelPipeline p = ...;
  ...
  p.addLast("serverCodec", new HttpServerCodec());
  p.addLast("respondExpectContinue", new HttpServerExpectContinueHandler());
  ...
  p.addLast("handler", new HttpRequestHandler());
