cgi

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.
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.
