Where can I see the content of Channel.write()

Question

I'm new to netty and trying the examples they have on their website. I'm doing the HttpFileServer for version 3.9 and and in the Handler class I saw this

    Channel ch = e.getChannel();

    // Write the initial line and the header.
    ch.write(response);

Where/how can I see what is being written to the a channel instance?

Answer 1

You can add a LoggingHandler to the ChannelPipeline. This will log out all the data which is received and written.
