FLASK_STATIC_DIGEST_BLACKLIST_FILTER = []
# If you want specific extensions to not get md5 tagged you can add them to
# the list, such as: [".htm", ".html", ".txt"]. Make sure to include the ".".
FLASK_STATIC_DIGEST_GZIP_FILES = True
# When set to False then gzipped files will not be created but static files
# will still get md5 tagged.
FLASK_STATIC_DIGEST_HOST_URL = None
# When set to a value such as https://cdn.example.com and you use static_url_for
# it will prefix your static path with this URL. This would be useful if you
# host your files from a CDN. Make sure to include the protocol (aka. https://).
