Fails path when works behind nginx for example. Make option to use relative paths. about serve-index HOT 1 CLOSED

Hi @Delagen ! So there was a very long issue over at expressjs/serve-static#9 which details this same issue and why these two modules cannot use relative redirects. The simple example: A request comes in to http://server/instance and Express sees http://ip/. How can it redirect to http://server/instance/ (i.e. add the trailing slash so the relative links in your index.html file work)? It cannot, especially since as far as it can tell there is already a railing slash.

There are two solutions you'll need to implement. The best solution is to have nginx pass back http://server/instance/ as part of the request; probably a special request header like X-Original-Url. Then simply set req.originalUrl to that value somewhere above this middleware. Everything will now work just fine. Example:

app.use(function (req, res, next) {
  req.originalUrl = req.headers['x-original-url'] || undefined
  next()
})

The second is to accept that it would be impossible to use this module in your root path and just rewrite the Location header, as described in the link above.

from serve-index.
