If you wish to workout your application on any sort of directory structure then you will require parent path enabled for your domain on your web server. It will allow you to use “..” while browsing directories of your domain. You will need to enable it explicitly as Parent Path will not be enabled by default in IIS.
How to enable it?
Below are the steps to enable parent path in IIS:
1. In IIS Manager, right click on domain name and then click Properties.
2. Click the Directory tab, and then click Configuration.
3. Click the Options tab.
4. In the Application configuration section, select the Enable parent paths check box.
5. Click OK.
