use ApplicationProtocolConfig

Use CorsConfigBuilder instead.

use Http2FrameCodecBuilder together with Http2MultiplexHandler.

use ApplicationProtocolConfig.

use ApplicationProtocolConfig.

Use DomainWildcardMappingBuilder instead.

Use DomainWildcardMappingBuilder

Use ChannelOption.WRITE_BUFFER_WATER_MARK

Use ChannelOption.TCP_FASTOPEN instead.

Use Epoll.isTcpFastOpenClientSideAvailable() or Epoll.isTcpFastOpenServerSideAvailable().

use HttpHeaderNames.CONNECTION "keep-alive"

SSLv2 is no longer secure. Consider using SslProtocols.TLS_v1_2 or SslProtocols.TLS_v1_3

SSLv3 is no longer secure. Consider using SslProtocols.TLS_v1_2 or SslProtocols.TLS_v1_3

TLSv1.1 is no longer secure. Consider using SslProtocols.TLS_v1_2 or SslProtocols.TLS_v1_3

Use ServerBootstrap.config() instead.

no use-case for this.

use ChannelConfig.getBufferAllocator()

use ChannelConfig.setBufferAllocator(BufferAllocator)

Use AttributeMap.hasAttr(AttributeKey)

use EmbeddedChannel.inboundMessages()

use EpollSocketChannelConfig.setTcpKeepCnt(int)

This method will be removed in the next major feature release. Deregister all Channels in this group from their EventLoop. Please note that this operation is asynchronous as Channel.deregister() is.

Use AbstractNioChannel.clearReadPending() if appropriate instead. No longer supported.

Use CorsConfigBuilder.allowedRequestHeaders(String...) instead.

Use CorsConfigBuilder.allowNullOrigin() instead.

Use CorsConfigBuilder.disable() instead.

Use CorsConfigBuilder.maxAge(long) instead.

Use CorsConfigBuilder.preflightResponseHeader(CharSequence, Object...) instead.

Use CorsConfig.isShortCircuit() instead.

Use CorsConfigBuilder.forOrigin(String) instead.

Use HttpHeaders.add(CharSequence, Object) instead.

Use HttpHeaders.clear() instead. Removes all headers from the specified message.

Use AsciiString.contentEqualsIgnoreCase(CharSequence, CharSequence) instead.

Use HttpHeaders.getTimeMillis(CharSequence) instead. Returns the value of the "Date" header.

Use HttpHeaders.get(CharSequence) instead.

Use HttpHeaders.getInt(CharSequence) instead.

Use HttpUtil.isContentLengthSet(HttpMessage) instead.

Use HttpUtil.isTransferEncodingChunked(HttpMessage) instead. Checks to see if the transfer encoding in a specified HttpMessage is chunked

Use AsciiString instead.

Create a new CharSequence which is optimized for reuse as HttpHeaders name or value. So if you have a Header name or value that you want to reuse you should make use of this.

Use HttpUtil.setTransferEncodingChunked(HttpMessage, boolean) instead.

Use HttpUtil.setContentLength(HttpMessage, long) instead.

Use HttpHeaders.set(CharSequence, Object) instead.

Use HttpHeaders.set(CharSequence, Object) instead.

Use HttpUtil.setKeepAlive(HttpMessage, boolean) instead. Sets the value of the "Connection" header depending on the protocol version of the specified message. This getMethod sets or removes the "Connection" header depending on what the default keep alive mode of the message's protocol version is, as specified by HttpVersion.isKeepAliveDefault().

• If the connection is kept alive by default:
  • set to "close" if keepAlive is false.
  • remove otherwise.
• If the connection is closed by default:
  • set to "keep-alive" if keepAlive is true.
  • remove otherwise.

Use HttpMessage.protocolVersion() instead.

Use WebSocketChunkedInput.readChunk(ByteBufAllocator). Fetches a chunked data from the stream. Once this method returns the last chunk and thus the stream has reached at its end, any subsequent WebSocketChunkedInput.isEndOfInput() call must return true.

Huffman decoding no longer depends on having a decode capacity.

will be removed.

use SslProvider.isAlpnSupported(SslProvider) with SslProvider.OPENSSL.

use OpenSslSessionContext.setTicketKeys(OpenSslSessionTicketKey...).

use SslContextBuilder.option(SslContextOption, Object) with OpenSslContextOption.USE_TASKS.

use {@link #sessionContext#stats()}

Replaced by SslContextBuilder

use SslHandler.getCloseNotifyFlushTimeoutMillis()

use SslHandler.setCloseNotifyFlushTimeoutMillis(long)

Use ChunkedInput.readChunk(ByteBufAllocator).

Fetches a chunked data from the stream. Once this method returns the last chunk and thus the stream has reached at its end, any subsequent ChunkedInput.isEndOfInput() call must return true.

Use DnsNameResolverBuilder.authoritativeDnsServerCache(AuthoritativeDnsServerCache)

Use DefaultDnsServerAddressStreamProvider.defaultAddressList().

Returns the list of the system DNS server addresses. If it failed to retrieve the list of the system DNS server addresses from the environment, it will return "8.8.8.8" and "8.8.4.4", the addresses of the Google public DNS servers.

please consider using Attribute.set(Object) (with value of null).

Use CharsetUtil.encoder(Charset).

use DomainNameMappingBuilder to create and fill the mapping instead

This method will no longer be invoked by ResourceLeakDetector.

Use CorsConfigBuilder instead.

use ChunkedWriteHandler()

use DomainNameMappingBuilder to create and fill the mapping instead

Use JdkLoggerFactory.INSTANCE instead.

Use Slf4JLoggerFactory.INSTANCE instead.
