HTTP 100 Continue vs 226 IM Used
HTTP 100 (Continue) is a 1xx Informational response, while 226 (IM Used) 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, 226 means that the server has fulfilled a GET request for the resource, and the response is a representation of the result of one or more instance-manipulations.
