The State Threads Library is a small application library which provides
a foundation for writing fast and highly scalable Internet applications
(such as web servers, proxy servers, mail transfer agents, and so on,
really any network-data-driven application) on UNIX-like platforms. It
combines the simplicity of the multithreaded programming paradigm, in
which one thread supports each simultaneous connection, with the
performance and scalability of an event-driven state machine
architecture. In other words, this library offers a threading API for
structuring an Internet application as a state machine. For more
details, please see the library documentation.
The State Threads library is a derivative of the Netscape Portable Runtime library (NSPR) and therefore is distributed under the Mozilla Public License (MPL) version 1.1 or the GNU General Public License (GPL) version 2 or later.
