lua-wsapi

WSAPI is an API that abstracts the web server from Lua web

applications. By coding against WSAPI your application can run on any of the supported servers and interfaces (currently CGI, FastCGI and Xavante, on Windows and UNIX-based systems). WSAPI provides a set of helper libraries that help with request processing and output buffering. You can also write applications that act as filters that provide some kind of service to other applications, such as authentication, file uploads, request isolation, or multiplexing. WSAPI's main influence is Ruby's Rack framework, but it was also influenced by Python's WSGI (PEP 333). It's not a direct clone of either of them, though, and tries to follow standard Lua idioms.
