There is a CDNS settings, that can contain a list of (cdn name, protocol)

tuples; for example:

  CDNS = [('google', 'https')]

    try:

        # list of tuples of the form (cdnname, protocol)

        cdns = settings.CDNS

    except AttributeError:

        cdns = []

    if cdns:

        modname = str(modname.replace('-', '_'))

        pkg = __import__('xstatic.pkg', fromlist=[modname])

        mod = getattr(pkg, modname)

        for cdnname, protocol in cdns:

            try:

                base_url = XStatic(mod, provider=cdnname, protocol=protocol).base_url

            except KeyError:

                continue

            if isinstance(base_url, str):

                # base_url is often a str

                return base_url + '/' + filename

            else:

                # But it also can be a dict (which maps relative paths to

                # full urls) (this happens with jquery CDN)

                if filename in base_url:

                    return base_url.get(filename)
