access js file from another website

In IIS, i have a website under which there are various virtual directories. I want to access/link JS file from one virtual directory into another. So, basically i have an application (in virtual dir 1) from which i want to link JS files being used in another application (virtual dir 2). Both these applications are under the same website in IIS.

Also, i am looking at a way of 开发者_高级运维creating a common folder under website from where all applications can link commonly used JS files. Any ideas on how this can be done?

You can add reference like...

<script src="http://www.website.com/foldername/GeneralMethods.js" type="text/javascript"></script>
