What is the UNLOCK method?
The UNLOCK method is a WebDAV extension (RFC 4918) used by clients to release a lock previously taken on a resource, identified by its lock token.
API Usage & Best Practices
- Provide the Lock-Token: Supply the
Lock-Tokenheader naming the exact lock to remove, or the server cannot honor the request. - Release when done: Always unlock as soon as editing finishes so other clients are not blocked longer than necessary.
- Idempotent removal: Once a lock is gone the resource is simply unlocked, so repeating UNLOCK leaves the same end state.
Common Response Codes
- 204 No Content: The lock was removed successfully.
- 409 Conflict: The supplied lock token does not match a lock on the resource.
