多人在线的网络聊天室—服务器，简化实用 可以修改后添加其他功能(Multiplayer online chat rooms- server, simplifying practical Other functions can be modified to add)

从libnids得到TCP重组的数据，当libnids的状态为NIDS_JUST_EST时，表示TCP建立连接，在此时给TCP流增加一个flow_id用来标识此连接；当libnids的状态为NIDS_DATA时，表示接受数据，当有新的数据到达时，根据flow_id把数据push到相应的流表中，为之后的数据分析做准备。因此，可以在此框架上增加符合http协议的应用解析(Data TCP libnids restructuring, when libnids status to NIDS_JUST_EST, said the TCP connection is established, at the same time adds a flow_id to TCP flow is used to identify this connection When libnids status to NIDS_DATA, accepted data, when new data arrives, according to flow_id to push data to the corresponding flow table, prepare the way for after data analysis. Can be increased on this framework, therefore, in accordance with the application of the HTTP protocol parsing)
