        Keyword arguments:
            content_type - Filetype. By default - None means auto-detect.
            max_age - Cache control. How long browser can keep this file on disk.
                      By default - 30 days
                      Set to 0 - to disable caching.

        Example 1: Default use case:

        Example 2: Disable caching:
