protected void addSpdyHandlers(io.netty.channel.ChannelHandlerContext ctx,
                   int version)

Add all ChannelHandler's that are needed for SPDY with the given version.

addHttpHandlers

protected void addHttpHandlers(io.netty.channel.ChannelHandlerContext ctx)

Add all ChannelHandler's that are needed for HTTP.

createHttpRequestHandlerForHttp

protected abstract io.netty.channel.ChannelInboundHandler createHttpRequestHandlerForHttp()

Create the ChannelInboundHandler that is responsible for handling the http requests when the SpdyOrHttpChooser.SelectedProtocol was SpdyOrHttpChooser.SelectedProtocol.HTTP_1_0 or SpdyOrHttpChooser.SelectedProtocol.HTTP_1_1

createHttpRequestHandlerForSpdy

protected io.netty.channel.ChannelInboundHandler createHttpRequestHandlerForSpdy()

Create the ChannelInboundHandler that is responsible for handling the http responses when the SpdyOrHttpChooser.SelectedProtocol was SpdyOrHttpChooser.SelectedProtocol.SPDY_2 or SpdyOrHttpChooser.SelectedProtocol.SPDY_3. By default this getMethod will just delecate to createHttpRequestHandlerForHttp(), but sub-classes may override this to change the behaviour.
