I have a website with `index.html` in the root folder, and a folder named `apples`. Inside `apples` I have another `index.html`. Currently I am attempting to use AngularJS to load the same navbar into both pages. However, when I tried linking to the Javascript file like so: `<script src="/controller.js">`, the JS file loads for the `index.html` in the root folder, but it refuses to load the file for the `index.html` in the `apples` folder. Does anyone know why? In the `apples` folder, it keeps linking to `apples//controller.js`.
