HTTP 100 Continue vs 507 Insufficient Storage
HTTP 100 (Continue) is a 1xx Informational response, while 507 (Insufficient Storage) is a 5xx Server Error response. 100 indicates that the server has received the request headers and the client should proceed to send the request body. This lets the client know it can continue with the request or abort if the headers were rejected. In contrast, 507 means that the server is unable to store the representation needed to complete the request (WebDAV).
