Class HttpRequestDecoder

  • All Implemented Interfaces:
    ChannelHandler, ChannelUpstreamHandler, LifeCycleAwareChannelHandler
    public class HttpRequestDecoder
extends HttpMessageDecoder
    Decodes ChannelBuffers into HttpRequests and HttpChunks.

    Parameters that prevents excessive memory consumption

    NameMeaning
    maxInitialLineLength The maximum length of the initial line (e.g. "GET / HTTP/1.0") If the length of the initial line exceeds this value, a TooLongFrameException will be raised.
    maxHeaderSize The maximum length of all headers. If the sum of the length of each header exceeds this value, a TooLongFrameException will be raised.
    maxChunkSize The maximum length of the content or each chunk. If the content length exceeds this value, the transfer encoding of the decoded request will be converted to 'chunked' and the content will be split into multiple HttpChunks. If the transfer encoding of the HTTP request is 'chunked' already, each chunk will be split into smaller chunks if the length of the chunk exceeds this value. If you prefer not to handle HttpChunks in your handler, insert HttpChunkAggregator after this decoder in the ChannelPipeline.
