Class Netcgi_common.cgi


class cgi : cgi_environment -> output_type -> request_method -> cgi_argument list -> object .. end
cgi env op meth args constructs Netcgi.cgi objects. The environment #out_channel is wrapped into a transactional channel or a discarding channel according to op (`Direct or `Transactional) and request_method (`HEAD requests must only return a header). For standard cases, when POST and PUT arguments are available through a Netchannels.in_obj_channel, we recommend you use Netcgi_common.cgi_with_args that will parse the arguments for you and check preconditions.

Remark: You may think that the argument meth is superfluous as it can be deduced from env#cgi_request_method. While it is true for `DELETE, `GET, `HEAD and `POST, the `PUT takes a Netcgi_common.cgi_argument parameter. Setting correctly this parameter and decoding env#cgi_request_method is done for you by Netcgi_common.cgi_with_args.
