The relative-Redirect functionality of the app redirects the visitors to the exact same page path as the destination URL.

For Example: If someone visits from country France (FR) to the URL of the US store “.com/products/shirt” then by the relative-redirect feature they will be redirected to the same page path like “.com/en-fr/products/shirt”

To enable the feature go to app > Redirect Settings > Preserve URL Path> Click to Enable (Green)

Please note that when a visitor is redirected and the same page URL is not present on the other website then it will show a 404 error.
