We are trying to make a connection to a other service for my company and the webservice is hosted over a VPN on port 444 with SSL. I am just wondering why you should NOT want to use the standarized port for SSL, 443. Of course it's theoretically possible to host SSL/HTTP communication over any port other than 443 but I don't see a reason to do it.
The only reason I can imagine is that your webservices are routed based on the port number. So 443 goes to internal application X and 444 goes to internal application.
Can somebody give me some insights?
