CGI is very simple… all you need is in the script environment (as per os.getenv).
The URL parameters are in QUERY_STRING. So os.getenv( 'QUERY_STRING' ). They are URL-encoded, so you need to decode them before using them. See example bellow.
For a POST, the parameters are in the request body. So you need to get the length of the content (os.getenv( "CONTENT_LENGTH" ) ), then read that much from io.stdin. Again, the parameters will be encoded ( 'application/x-www-form-urlencoded' usually, possibly 'multipart/form-data'). You will need to decode them as well.
Etc, etc, etc...
Here are some details about CGI:
The Common Gateway Interface (CGI) Version 1.1
http://www.ietf.org/rfc/rfc3875
And a little usage example.
