HTTP 203 Non-Authoritative Information vs 424 Failed Dependency
HTTP 203 (Non-Authoritative Information) is a 2xx Success response, while 424 (Failed Dependency) is a 4xx Client Error response. 203 indicates that the response payload has been modified by a transforming proxy from the origin server's 200 response. In contrast, 424 means that the request failed because it depended on another request that failed (WebDAV).
Description
The response payload has been modified by a transforming proxy from the origin server's 200 response.
When You See It
When a proxy or CDN modifies the response body (e.g., adds headers, transforms content).
How to Fix
Check if a proxy is modifying the response. Access the origin directly if you need the original content.
Description
The request failed because it depended on another request that failed (WebDAV).
When You See It
In batch WebDAV operations when a prerequisite action fails.
How to Fix
Fix the failed dependency first, then retry the operation.
