Choose between a normal Web server (HTTP) and a secure Web server (HTTPS)

Choose "Secure Web server (HTTPS)" if you want all the data exchanged between XMLmind XSL Server and its clients (e.g. a Web browser) to be encrypted. Otherwise, choose "Web server (HTTP)".
Note that the confidentiality provided by option "Secure Web server (HTTPS)" is really not useful if you intend to operate XMLmind XSL Server on your local network.
