Yeah, I know. Parent was saying that the History API doesn't need any server support, because you can just serve the same file no matter what the subpath, but my point is that lots of servers don't even have support for that. That's why the fragment is still more useful than the History API in some cases.
Fair point, thanks for adding this perspective! I of course assumed there was at least a modicum of control over this server side but as you correctly point out if there is no such control then shebang style navigation is your only option if indeed you must do client side routing. I once abused custom 404 pages (I think in GH pages, but it may have been some other free host with similar functionality) in order to achieve this kind of behaviour. It was just a demo so didn't matter much, but of course this is far from ideal for anything else.
