Zhan Chuan-jie · Journal of Nanchang University · 2005
Web based chat room has high server resource requirements due to its frequent client requests and limited response time. We employ Push Technology in web chat system to resolve this problem, and we provide a high performance realization of it on Microsoft Windows Operating System (WIN OS). By study of particular OS, we adopt such technologies as Multiple Threads and Microsoft Information Server API (ISAPI) in our realization. Compareing other Web Chat Systems on WIN OS, it has obvious performance advantage. We also present an information filter method in our system to guard the information security, and prevent the spread of harmful messages.
