  • Field Details

    • maxHeaderSize

      @ConfigItem(defaultValue="20K") public MemorySize maxHeaderSize
      The maximum length of all headers.

    • maxBodySize

      @ConfigItem(defaultValue="10240K") public Optional<MemorySize> maxBodySize
      The maximum size of a request body.

    • maxChunkSize

      @ConfigItem(defaultValue="8192") public MemorySize maxChunkSize
      The max HTTP chunk size

    • maxInitialLineLength

      @ConfigItem(defaultValue="4096") public int maxInitialLineLength
      The maximum length of the initial line (e.g. "GET / HTTP/1.0").

    • maxFormAttributeSize

      @ConfigItem(defaultValue="2048") public MemorySize maxFormAttributeSize
      The maximum length of a form attribute.

    • maxFormFields

      @ConfigItem(defaultValue="256") public int maxFormFields
      Set the maximum number of fields of a form. Set to -1 to allow unlimited number of attributes.

    • maxFormBufferedBytes

      @ConfigItem(defaultValue="1K") public MemorySize maxFormBufferedBytes
      Set the maximum number of bytes a server can buffer when decoding a form. Set to -1 to allow unlimited length

    • maxParameters

      @ConfigItem(defaultValue="1000") public int maxParameters
      The maximum number of HTTP request parameters permitted for incoming requests.

      If a client sends more than this number of parameters in a request, the connection is closed.

    • maxConnections

      @ConfigItem public OptionalInt maxConnections
      The maximum number of connections that are allowed at any one time. If this is set it is recommended to set a short idle timeout.

    • headerTableSize

      @ConfigItem public OptionalLong headerTableSize
      Set the SETTINGS_HEADER_TABLE_SIZE HTTP/2 setting.

      Allows the sender to inform the remote endpoint of the maximum size of the header compression table used to decode header blocks, in octets. The encoder can select any size equal to or less than this value by using signaling specific to the header compression format inside a header block. The initial value is 4,096 octets.

    • maxConcurrentStreams

      @ConfigItem public OptionalLong maxConcurrentStreams
      Set SETTINGS_MAX_CONCURRENT_STREAMS HTTP/2 setting.

      Indicates the maximum number of concurrent streams that the sender will allow. This limit is directional: it applies to the number of streams that the sender permits the receiver to create. Initially, there is no limit to this value. It is recommended that this value be no smaller than 100, to not unnecessarily limit parallelism.

    • maxFrameSize

      @ConfigItem public OptionalInt maxFrameSize
      Set the SETTINGS_MAX_FRAME_SIZE HTTP/2 setting. Indicates the size of the largest frame payload that the sender is willing to receive, in octets. The initial value is 2^14 (16,384) octets.

    • maxHeaderListSize

      @ConfigItem public OptionalLong maxHeaderListSize
      Set the SETTINGS_MAX_HEADER_LIST_SIZE HTTP/2 setting. This advisory setting informs a peer of the maximum size of header list that the sender is prepared to accept, in octets. The value is based on the uncompressed size of header fields, including the length of the name and value in octets plus an overhead of 32 octets for each header field. The default value is 8192

    • rstFloodMaxRstFramePerWindow

      @ConfigItem public OptionalInt rstFloodMaxRstFramePerWindow
      Set the max number of RST frame allowed per time window, this is used to prevent HTTP/2 RST frame flood DDOS attacks. The default value is 200, setting zero or a negative value, disables flood protection.

    • rstFloodWindowDuration

      @ConfigItem public Optional<Duration> rstFloodWindowDuration
      Set the duration of the time window when checking the max number of RST frames, this is used to prevent HTTP/2 RST frame flood DDOS attacks.. The default value is 30 s, setting zero or a negative value, disables flood protection.
