LuaSocket is a Lua extension library that is composed by two parts: a C core that provides support for the TCP and UDP transport layers, and a set of Lua modules that add support for functionality commonly needed by applications that deal with the Internet.
The core support has been implemented so that it is both efficient and simple to use. It is available to any Lua application once it has been properly initialized by the interpreter in use. The code has been tested and runs well on several Windows and Unix platforms.
Among the support modules, the most commonly used implement the SMTP (sending e-mails), HTTP (WWW access) and FTP (uploading and downloading files) client protocols. These provide a very natural and generic interface to the functionality defined by each protocol. In addition, you will find that the MIME (common encodings), URL (anything you could possible want to do with one) and LTN12 (filters, sinks, sources and pumps) modules can be very handy.
The library is available under the same terms and conditions as the Lua language, the MIT license. The idea is that if you can use Lua in a project, you should also be able to use LuaSocket.

Throughout LuaSocket's history, many people gave suggestions that helped improve it. For that, I thank the Lua community. Special thanks go to David Burgess, who has helped push the library to a new level of quality and from whom I have learned a lot of stuff that doesn't show up in RFCs. Special thanks also to Carlos Cassino, who played a big part in the extensible design seen in the C core of LuaSocket 2.0. Mike Pall has been helping a lot too! Thanks to you all!
