508 Loop Detected

The HTTP 508 Loop Detectedserver error response status code indicates that the entire operation failed because it encountered an infinite loop while processing a request with Depth: infinity.

The status may be given in the context of the Web Distributed Authoring and Versioning (WebDAV). It was introduced as a fallback for cases where WebDAV clients do not support 208 Already Reported responses (when requests do not explicitly include a DAV header).
