Class HttpRequestDecoder

  • All Implemented Interfaces:
    ChannelHandler

    public class HttpRequestDecoder
    extends HttpObjectDecoder
    Decodes Buffers into HttpRequests and HttpContents.

    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 TooLongHttpLineException will be raised.
    maxHeaderSize The maximum length of all headers. If the sum of the length of each header exceeds this value, a TooLongHttpHeaderException 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 HttpContents. 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 HttpContents in your handler, insert HttpObjectAggregator after this decoder in the ChannelPipeline.
