Secure Uploads

I’ve got a quick hack that I think would provide secure uploads for login-required sites.

Basically, you set up NGINX Docs | Authentication Based on Subrequest Result for uploads. The only issue is that I can’t find a URL that returns a 403/401 when login-required is turned on, so accessing an upload when you’re not logged in gives a 500 error. This would only happen if someone had an upload URL and tried to access it when they weren’t logged in, so it doesn’t seem that bad.

It’s something like this:

# JP
    location = /auth {
        proxy_pass http://discourse/categories;
        proxy_pass_request_body off;
        proxy_set_header Content-Length "";
        proxy_set_header X-Original-URI $request_uri;
    # END JP
    location ~ ^/uploads/ {

      auth_request /auth; #$JP
      # NOTE: it is really annoying that we can't just define headers
      # at the top level and inherit.
