Constructor Detail

HttpHeaderReader

public HttpHeaderReader(java.nio.channels.SocketChannel channel,
                        BufferHandle bh,
                        NioHandler nioHandler,
                        TrafficLogger tl,
                        boolean request,
                        boolean strictHttp,
                        HttpHeaderListener reader)

Parameters:

channel - the SocketChannel to read from

bh - the BufferHandle to use to get ByteBuffers

nioHandler - the NioHandler to use to wait for more data

tl - the TrafficLogger to update with network read Statistics

request - true if a request is read, false if a response is read. Servers may respond without header (HTTP/0.9) so try to handle that.

strictHttp - if true http headers will be strictly parsed, if false http newlines may be single \n

reader - the listener for http headers
