-### 1. StatusCodeRange
-
-- Response status code range. If StatusCode is configured, this validation condition will be ignored.
-- Valid configuration examples:
- 1. One of `"3xx"`, `"4xx"`, `"5xx"`
- 2. Specific HTTP return codes, consistent with the StatusCode function
- 3. The above (1) or (2) connected by the `"|"` symbol, for example:
- - `"503|4xx"`
- - `"501|409|30x"`
