HTTP 100 Continue vs 200 OK
HTTP 100 (Continue) is a 1xx Informational response, while 200 (OK) is a 2xx Success 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, 200 means that the request succeeded. The meaning depends on the HTTP method: GET returns the resource, POST reports the action result, HEAD returns headers only.
