LuaSocket is a Lua extension library that helps to add support for functionality commonly needed by applications that deal with the Internet. It provides easy access to TCP, UDP, DNS, SMTP, FTP, HTTP, MIME and more.

LuaSocket is a 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.

Author: Diego Nehab

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.
