micronaut.server.netty.close-on-expectation-failed

boolean

If a 100-continue response is detected but the content length is too large then true means close the connection. otherwise the connection will remain open and data will be consumed and discarded until the next request is received.

<p>only relevant when {@link HttpServerType#FULL_CONTENT} is set</p>

micronaut.server.netty.fallback-protocol

java.lang.String

micronaut.server.netty.log-level

io.netty.handler.logging.LogLevel

The server {@link LogLevel} to enable.

micronaut.server.netty.max-initial-line-length

int

The maximum length of the initial HTTP request line. Defaults to 4096.

micronaut.server.netty.max-header-size

int

The maximum size of an individual HTTP setter. Defaults to 8192.

micronaut.server.netty.max-chunk-size

int

The maximum chunk size. Defaults to 8192.

micronaut.server.netty.max-h2c-upgrade-request-size

int

The maximum size of the body of the HTTP1.1 request used to upgrade a connection to HTTP2 clear-text (h2c). This initial request cannot be streamed and is instead buffered in full, so the default value (8192) is relatively small. <i>If this value is too small for your use case, instead consider using an empty initial "upgrade request" (e.g. {@code OPTIONS /}), or switch to normal HTTP2.</i> <p> <i>Does not affect normal HTTP2 (TLS).</i>

micronaut.server.netty.chunked-supported

boolean

Whether chunked requests are supported.

micronaut.server.netty.use-native-transport

boolean

Whether to use netty’s native transport (epoll or kqueue) if available.

micronaut.server.netty.validate-headers

boolean

Whether to validate headers.

micronaut.server.netty.initial-buffer-size

int

The initial buffer size. Defaults to 128.

micronaut.server.netty.compression-threshold

int

The default compression threshold. Defaults to 1024. <p> A value {@code < 0} indicates compression should never be enabled.

micronaut.server.netty.compression-level

int

The default compression level. Default value (6).

micronaut.server.netty.child-options

micronaut.server.netty.keep-alive-on-server-error

boolean

micronaut.server.netty.pcap-logging-path-pattern

java.lang.String

The path pattern to use for logging incoming connections to pcap. This is an unsupported option: Behavior may change, or it may disappear entirely, without notice!

micronaut.server.netty.listeners

java.util.List

Get the explicit netty listener configurations, or {@code null} if they should be implicit.

micronaut.server.netty.eager-parsing

boolean

Parse incoming JSON data eagerly, before route binding. Default value {@value DEFAULT_EAGER_PARSING}.

micronaut.server.netty.json-buffer-max-components

int

Maximum number of buffers to keep around in JSON parsing before they should be consolidated. Defaults to 4096.

micronaut.server.netty.legacy-multiplex-handlers

boolean

Prior to 4.4.0, the Micronaut HTTP server used a multi-pipeline approach for handling HTTP/2 connections where every request got its own netty pipeline with HTTP/2 to HTTP/1.1 converters on the pipeline. This allowed for using mostly unchanged HTTP/1.1 in the request handling and any NettyServerCustomizers. <p> As of 4.4.0, this approach was replaced with a more performant HTTP/2-specific implementation. This means worse compatibility with HTTP/1.1-based code paths and customizers, however. Setting this option to {@code true} returns to the old behavior.
