You can run the UI Engine as a helper application for a configured ulc MIME type. To add the UI Engine as a helper application, follow the instructions listed for your browser:
After you configure the UI Engine as a helper in Windows, clicking on any file with the extension .ulc causes the UI Engine to start and attempt to connect to the application referred to within the .ulc file. For example:
If you now start the Dossier application as a server on port 4444 and then click on the dossier.ulc file, a connection is established to the Dossier server.
If the dossier.ulc file is referred to in a hyperlink on a Web page, clicking on the link starts a connection between the UI Engine and the ULC application server. In addition, if you use the ULC HTTP server, you can replace the host name with $WEBHOST, and the ULC HTTP server replaces the token with the name of the host on which the HTTP server is running.
