HTTP Redirect to HTTPS

1 - Create a folder inside the wwwroot folder on the webserver. You can call it anything you like. I'm going to call it HTTP for this example. The wwwroot folder is usually found at :\inetpub\wwwroot

2 - In IIS add a website

3   - Set the site name to match the folder you created

- Set the Physical path to the folder you created in step 1

- Set the binding hostname to the HTTP DNS address of your site. It needs to match your DNS A record exactly. If you used a fully qualified name then put a fully qualified name. 

4 In IIS highlight the site you just created and open HTTP Redirect

5 Check the box next to Redirect, enter the HTTPS address of your site.

- Check the box "Redirect all requests to exact destination"
