Radicale Server module.
|
|
|
|
This module offers 3 useful classes:
|
|
|
|
- ``HTTPServer`` is a simple HTTP server;
|
|
- ``HTTPSServer`` is a HTTPS server, wrapping the HTTP server in a socket
|
|
managing SSL connections;
|
|
- ``CalendarHTTPHandler`` is a CalDAV request handler for HTTP(S) servers.
|
|
|
|
To use this module, you should take a look at the file ``radicale.py`` that
|
|
should have been included in this package.
