Code example to write asynchronous server

[yanky young]

Hi:

I am not netty expert yet. I am just trying to give some hints. In your
case, you are actually building a request/response protocol. And request and
response message may include quite complicated headers and body. So you have
to do some message encoding and decoding in both server side and client
side. You can see in netty codebase there are some out-of-box encoder and
decoder in handler.codec package. I suggest you take a look at
example.fractorial package to see how to implement your own encoder and
decoder for your message format which may be xml. If you are not sensitive
to message format, you can also have a look at example.localtime which use
google protobuf library as real encoder and decoder.

good luck
