Why is IIS redirecting (Rewrite) HTTPS request to port 80?

Question

IIS

The idea is to redirect all direct attempts to download a file to a special address: https://mysite.com/getfile/?fname=media/upload/use... }
The difficulty of debugging rewrite in Azure prevents me from getting to the bottom of it. Maybe you can see where the rake is?

        Этот блок должен всегда выполняться при попытке прямого доступа в папку /media/upload/users/

        https://mysite:80/media/upload/users/...
        и на странице показывает ошибку 404.4
        Проблема в том, что HTTPS это порт 443.

Answer 1

Isn't that the rule?
rule name="Redirect to https" stopProcessing="true" enabled="true"
