'secured' option specifies that Pliant should also listing on another TCP port for secured connections.
The default port used by Pliant secured connections is 580, or more pecisely, the port used by clear conenctions plus 500.

Please also notice that Pliant HTTP server does not use SSL for secured connections but the much more powerfull (and still probably less secured at the moment since it needs reviewing) Pliant crypto system.

An example:

pliant module /pliant/protocol/http/server.pli command 'http_server secured'
