HTTP Status Codes

424 Failed Dependency

A WebDAV status meaning the request failed because an action it depended on — often an earlier request in the same operation — did not succeed.

What it means

424 Failed Dependency (RFC 4918) indicates the method could not be performed because it depended on another action that failed, such as a member of a batch whose predecessor errored. It signals a cascade rather than an intrinsic problem with this request.

Why it matters

  • It explains cascading failures in multi-step WebDAV operations.

Common mistakes

  • Using 424 outside dependency-aware WebDAV flows.

How WebInspect checks this

  • WebInspect surfaces the status within multistatus responses without alteration.
