Inherits

- `Netcgi.cgi`

    method role : [ `Authorizer | `Filter | `Responder ]

A FastCGI application can fulfill each of the following three roles:

- ``Responder`: This is the usual role. In this case the application is expected to act like a CGI program: It receives all the information associated with an HTTP request and generates an HTTP response.

- ``Authorizer`: An Authorizer FastCGI application receives all the information associated with an HTTP request and generates an authorized/unauthorized decision.

- ``Filter`: A Filter FastCGI application receives all the information associated with an HTTP request, plus an extra stream of data from a file stored on the Web server, and generates a "filtered" version of the data stream as an HTTP response.

    method data : Netchannels.in_obj_channel

This the the channel on which the filter data is available. All methods of the object raise `Netchannels.Closed_channel` if the role is not ``Filter`.

    method data_length : int

How many bytes of the data are available.

    method data_mtime : float

The data last modification time, expressed as an integer number of seconds since the epoch (January 1, 1970 UTC).
