Sharepoint - Redirect HTTP to HTTPS

There are some online-tipps which recommend the use of the IIS Rewrite module. I do not prefer this way.

• Alternate Access Mappings: Configure your HTTPS URL in Default-Zone. Add an additional "Internal URL" and map it to the "Default" Zone. Should look like this:

This configuration will redirect your users from HTTP to HTTPS even if they call a subsite of SharePoint.
