Setting up a Windows IIS7 subdirectory to point to a WordPress on apache server

We have an existing site, and want to set up IIS7 so that when patrons access a URL subdirectory like https://www.mywebsite.org/tutorials they’ll be directed to a WordPress site that is installed on a Debian Linux apache web-server, but the https://www.mywebsite.org/tutorials URL will continue to show in the web address bar. We do not want to install WordPress on the existing Windows server, as we already have our WordPress site up and running on the Apache server, and that Windows server is already six years old and slated to be replaced in the not too distant future.
