This is a Haskell library for writing CGI programs. Its features include: - Access to CGI parameters (e.g. form input) from both GET and POST requests. - Access to CGI environment variables. - Ability to set arbitrary response headers. - Support for HTTP cookies. - An efficient implementation of multipart/form-data using Data.ByteString. This allows for efficient handling of file uploads. - Wrapper functions for compatibility with the old Network.CGI module. - A CGI monad transformer. - Basic exception handling and logging (these should be improved) - Low-level run functions that allow using programs written with this package with protocols other than CGI, for example FastCGI.
