025 * Default {@link HeadersMapFactory} which uses the {@link org.apache.camel.util.CaseInsensitiveMap CaseInsensitiveMap}.
026 * This implementation uses a {@link org.apache.camel.util.CaseInsensitiveMap} storing the headers.
027 * This allows us to be able to lookup headers using case insensitive keys, making it easier for end users
028 * as they do not have to be worried about using exact keys.
029 * See more details at {@link org.apache.camel.util.CaseInsensitiveMap}.
