All Implemented Interfaces:

io.netty5.channel.ChannelHandler, HttpClientUpgradeHandler.SourceCodec
```
public final class HttpClientCodec
extends io.netty5.channel.CombinedChannelDuplexHandler<HttpResponseDecoder,HttpRequestEncoder>
implements HttpClientUpgradeHandler.SourceCodec
```
A combination of HttpRequestEncoder and HttpResponseDecoder which enables easier client side HTTP implementation. HttpClientCodec provides additional state management for HEAD and CONNECT requests, which HttpResponseDecoder lacks. Please refer to HttpResponseDecoder to learn what additional state management needs to be done for HEAD and CONNECT and why HttpResponseDecoder can not handle it by itself. If the Channel is closed and there are missing responses, a PrematureChannelClosureException is thrown.
