1The State Threads is a small application library which provides a 2foundation for writing fast and highly scalable Internet applications 3(such as web servers, proxy servers, mail transfer agents, and so on) on 4UNIX-like platforms. It combines the simplicity of the multithreaded 5programming paradigm, in which one thread supports each simultaneous 6connection, with the performance and scalability of an event-driven 7state machine architecture. In other words, this library offers a 8threading API for structuring an Internet application as a state 9machine. 10 11The State Threads library is a derivative of the Netscape Portable 12Runtime library (NSPR). 13
