This meant that a file and all its resources could be loaded from a local directory or subdirectory during testing, without triggering a CORS error. URL endpoints have the following format: Follow these steps to create a function URL using the console.

Given that IdentityServer will most likely be hosted on a different origin than these clients, this implies that Cross-Origin Resource Sharing (CORS) will need to be configured.
