HTTP 101 Switching Protocols vs 424 Failed Dependency
HTTP 101 (Switching Protocols) is a 1xx Informational response, while 424 (Failed Dependency) is a 4xx Client Error response. 101 indicates that the server understands the Upgrade header field request and indicates which protocol it is switching to. In contrast, 424 means that the request failed because it depended on another request that failed (WebDAV).
