Automatic Code Downloading for Local Execution

• Using only the facilities presented, automatic LP/CLP code downloading for local execution is possible, using generic browsers.
• By simply clicking on a WWW pointer, and transparently for the user, remote code is automatically downloaded and locally queried via forms.
• Prerequisites:
  • The HTTP server on the server machine is configured to give a mime.type of application/x-prolog to the files with WWW-downloadable LP code.
  • The browser is configured to start helper wpl_handler when receiving data of type application/x-prolog (this application starts the LP engine as an active module).
  • There is a local cgi-bin executable wpl_questioner.cgi (which uses that active module).
