If you don't know how to the the HTTP server and log as administrator, the simplest is probably to just type in:

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

and connect to it through typing http://localhost/ in your web browser,
or (if you already have an HTTP server running on port 80):

pliant module /pliant/protocol/http/server.pli command 'http_server port 8080 configure'

and connect to it through typing http://localhost:8080/
