ISAPI Redirect a URL to another URL

Question

I am new to Rewrite ISAPI and need help redirecting a URL from am existing to our standard IIS page.

Current page: https://store.md1.company.com/store/1/home

Redirect to https://store.md1.company.com

I currently use Helicon ISAPI 3 for all of my proxy rewrites and redirects, but I have tried a number of ways and I just can't get there. Any help would be greatly appreciated.

Code Tried:

RewriteEngine On

RewriteCond %{HTTP_HOST} ^store.md1.company\.com\/store/1/home$ [NC]
RewriteRule ^(.*)$ https://store.md1.company.com/$1 [QSA,R=301]
