All newer versions of Domino has an API endpoint for the Domino Rest API. If you have a domino server that you do not want to expose this endpoint on you can create some webserver redirections to turn this off. This is how you do it, first create a substitution rule to another location in this cased api2 and after that a redirection rule.
And after that create an redirection rule to you preferred destination
You could also redirect it to the newer Domino REST API on port 8880
You probably do not have that open externally.
Will the domino http server handle requests to this or does it handle the http requests on that port by it self?
