203 Non-Authoritative Information

Success

The server successfully processed the request, but is returning information that may be from another source.

Explanation

The 203 (Non-Authoritative Information) status code indicates that the request was successful but the enclosed payload has been modified from that of the origin server's 200 (OK) response by a transforming proxy. This status code allows the proxy to notify recipients when a transformation has been applied, since that knowledge might impact later decisions regarding the content.

For example, this can occur when an intermediary proxy modifies headers or content to comply with legal requirements or organizational policy.

Example Response
