i believe he is implying that his webhost has a strict filetype allowance, meaning files that aren’t basic html/php/css might not be allowed by default.
If you open the HTML file unity generates and find all instances (should be 2 I think, both in the head and the body - one each)of:
value="game.unity3d"
THAT is what is calling your game data.
You can host that HTML on any site and just edit:
value="game.unity3d"
With the above values, it looks in the root dir of the html file - or, right next to itself.
If your site is http://yoursite.com, and you want that file to be hosted on another site like google for example if you could upload it there, you would upload to, say, google.com/game/game.unity3d
then, you would update the HTML on yoursite.com to look like this:
value="http://google.com/game/game.unity3d"
So, that is your “path to the file”, no matter what site it is hosted on. Locally, it won’t need http://www.yoursite.com/, but remotely, you need to include all of that so that the browser knows to look outside of your domain for this element of the page, in this case, your game object.
Works on any and every embedded file, but I haven’t tested this. It’s basic embed source though, so it should work easily.
