use ApplicationProtocolConfig

Removed without alternatives.

use ApplicationProtocolConfig

Use DomainWildcardMappingBuilder}

Please use Log4J2LoggerFactory or Log4JLoggerFactory or Slf4JLoggerFactory.

Use MaxMessagesRecvBufferAllocator and MaxMessagesRecvBufferAllocator.maxMessagesPerRead(int).

Use ChannelOption.TCP_FASTOPEN_CONNECT instead.

use HttpHeaderNames.CONNECTION "proxy-connection"

SSLv2Hello is no longer secure. Consider using SslProtocols.TLS_v1_2 or SslProtocols.TLS_v1_3

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

Use ServerBootstrap.config() instead.

use EmbeddedChannel.outboundMessages()

Use FileRegion.transferred() instead.

Use ChannelGroup.writeAndFlush(Object) instead.

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

Use Errors.handleConnectErrno(String, int).

Use CorsConfigBuilder.allowCredentials() instead.

Use CorsConfigBuilder.allowedRequestMethods(HttpMethod...) instead.

Use CorsConfigBuilder.build() instead.

Use CorsConfigBuilder.exposeHeaders(String...) instead.

Use CorsConfigBuilder.noPreflightResponseHeaders() instead.

Use CorsConfigBuilder.shortCircuit() instead.

Use CorsConfigBuilder.forAnyOrigin() instead.

Use CorsConfigBuilder.forOrigins(String...) instead.

Use HttpHeaders.add(CharSequence, Object) instead.

Use HttpHeaders.add(CharSequence, Iterable) instead.

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 WebSocketServerHandshakerFactory.sendUnsupportedVersionResponse(Channel)

should not be used directly. Use Http2StreamChannelBootstrap.open() or Http2StreamChannelBootstrap.open(Promise)

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)

Override DnsAddressResolverGroup.newNameResolver(EventLoop, ChannelFactory, DnsServerAddressStreamProvider).

Use DefaultDnsServerAddressStreamProvider.defaultAddresses().

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

This method has the same effect with the following code:

 DnsServerAddresses.sequential(DnsServerAddresses.defaultAddressList());
 

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

Use CharsetUtil.decoder(Charset).

use ObjectPool.Handle.recycle(Object).

Use CorsConfigBuilder instead.

use ChunkedWriteHandler()

use DomainNameMappingBuilder to create and fill the mapping instead

Use JdkLoggerFactory.INSTANCE instead.

Use Slf4JLoggerFactory.INSTANCE instead.
