If you want to get your Prolog application to be accessible from an intranet or the Internet you can use this package to embed the Prolog programs into a .NET ASP page which can be served by e.g. Internet Information Services.
An example of how to do this is provided in pbnetexamples('prologasp.NET/eval.aspx'). Consult your IIS documentation for how to configure it for an ASPX page.
