Here's a good function header given the following:
I wrote the below code

    args = request.args
    headers = request.headers
    r = ParsedRequest()
    r.args = args
    settings = config.DOMAIN[resource]
    if settings['allowed_filters']:
        r.where = args.get(config.QUERY_WHERE)
    if settings['projection']:
        r.projection = args.get(config.QUERY_PROJECTION)
    if settings['sorting']:
        r.sort = args.get(config.QUERY_SORT)
    if settings['embedding']:
        r.embedded = args.get(config.QUERY_EMBEDDED)
    if settings['datasource']['aggregation']:
        r.aggregation = args.get(config.QUERY_AGGREGATION)
    r.show_deleted = (config.SHOW_DELETED_PARAM in args)
    max_results_default = (config.PAGINATION_DEFAULT if settings['pagination'] else 0)
    try:
        r.max_results = int(float(args[config.QUERY_MAX_RESULTS]))
        assert (r.max_results > 0)
    except (ValueError, werkzeug.exceptions.BadRequestKeyError, AssertionError):
        r.max_results = max_results_default
    if settings['pagination']:
        if (config.QUERY_PAGE in args):
            try:
                r.page = (abs(int(args.get(config.QUERY_PAGE))) or 1)
            except ValueError:
                pass
        if (r.max_results > config.PAGINATION_LIMIT):
            r.max_results = config.PAGINATION_LIMIT
    def etag_parse(challenge):
        if (challenge in headers):
            etag = headers[challenge]
            if etag.startswith('W/"'):
                etag = etag.lstrip('W/')
            return etag.replace('"', '')
        else:
            return None
    if headers:
        r.if_modified_since = weak_date(headers.get('If-Modified-Since'))
        r.if_none_match = etag_parse('If-None-Match')
        r.if_match = etag_parse('If-Match')
    return r

What's a good function header?
