Once you download the Experience, you just move it to your web server and unzip it there. Say I downloaded my experience, and I'd like people to find it at https://maps.co.kendall.il.us/mapviewer. I go into my web server machine (in this case, running Microsoft IIS) and browse to C:\inetpub\wwwroot\mapviewer and extract the zip file there. That's it!
The name of the URL just refers to the web server folder I've created to hold the files. Changing the name of the folder will update the URL.
Also, when you download an experience, the favicon is in the \cdn\0\assets folder (note that the 0 may change based on the download count). The first line of the index.html file has a tag for the shortcut icon, too, so you can re-write the tag to point to some other icon you have.
