2xxDetailed Explanation
HTTP 203 Non-Authoritative Information indicates the request was successful but the response body has been modified by a transforming proxy rather than the origin server. It informs the client that the received data may differ from what the origin server would have sent. In practice, this is a rarely used status code.
Common Causes
- ▸A transforming proxy modified the response body
- ▸A mirror server or caching layer altered the response content
- ▸A content-filtering proxy transformed the response data
How to Fix
- 1.203 is a normal response — no fix needed
- 2.If you need the original unmodified data, bypass the proxy or connect directly
- 3.If the modified content is unexpected, review the proxy configuration
