Changing the HTTP port of a Domino HTTP server

HCL Sametime installs on an HCL Domino server and uses the HTTP server provided with Domino.

About this task

To support the HTTP tunneling on port 80 functionality, the Community Mux on the server listens for HTTP connections from clients (including browsers) on port 80. If a browser connects to the Community Mux on port 80, and the Community Mux makes an intraserver connection to the Domino HTTP server on behalf of the browser on port 8088.

To enable HTTP tunneling on port 80, the Domino HTTP server port needs to be changed manually. It is recommended to change the Domino HTTP port to 8088.
