HTTP Status Codes

508 Loop Detected

A WebDAV status meaning the server aborted the request because processing it entered an infinite loop, often over cyclic resource bindings.

What it means

508 Loop Detected (RFC 5842) means the server detected an infinite loop while processing a request with Depth: infinity — for example cyclic bindings in a WebDAV collection — and terminated the operation to protect itself.

Why it matters

  • It stops runaway recursive operations from exhausting server resources.

Common mistakes

  • Creating cyclic WebDAV bindings that trigger infinite traversal.

How WebInspect checks this

  • WebInspect reports the status; 508 points at a recursive-processing loop on the origin.
