HTTPS browser connection for remote support through COM requires the use of a browser 'proxy auto-configuration' (.pac) file. The COM server hosts a .pac file, the address of which can be used for the connection.
The commands inside the .pac file look for a match to the URL entered in browser and, when a match occurs, redirects it. In this case, it redirects any request for a URL containing .maint. to COM. COM then uses the original address to route the request to the required customer server.
