This work is based on the original CGI interface that arose out of discussions on the 'www-talk' mailing list. In particular, Rob McCool, John Franks, Ari Luotonen, George Phillips and Tony Sanders deserve special recognition for their efforts in defining and implementing the early versions of this interface.

This document has also greatly benefited from the comments and suggestions made Chris Adie, Dave Kristol and Mike Meyer; also David Morris, Jeremy Madea, Patrick McManus, Adam Donahue, Ross Patterson and Harald Alvestrand.
