public class HttpServerExpectContinueHandler extends ChannelInboundHandlerAdapter
Sends a 100 CONTINUEHttpResponse
toHttpRequest
s which contain a 'expect: 100-continue' header. It should only be used for applications which do not install theHttpObjectAggregator
.By default it accepts all expectations.
Since
HttpServerExpectContinueHandler
expectsHttpRequest
s it should be added afterHttpServerCodec
but before any other handlers that might send aHttpResponse
.ChannelPipeline
p = ...; ... p.addLast("serverCodec", newHttpServerCodec
()); p.addLast("respondExpectContinue", newHttpServerExpectContinueHandler
()); ... p.addLast("handler", new HttpRequestHandler());
