URLs to .html without trailing slash and redirect

I have some routes that are pretending directly pointing to html files:

routes: [ 
...
  'pages/1.html',
  'pages/2.html',
...
]

and prerender-spa-plugin produces directory structure as:

pages/
└─1.html/
  └─index.html
└─2.html/
  └─index.html

The problem is that most of static web servers with such structure will issue a redirect from pages/1.html to pages/1.html/. Is there a way to specify output file per route to get structure like this?

pages/
└─1.html
└─2.html

Hmm, good idea. Perhaps I could add some logic to avoid outputting routes if there is a file extension on the route?

Works perfectly! 👍
