HTTP 100 Continue vs 404 Not Found
HTTP 100 (Continue) is a 1xx Informational response, while 404 (Not Found) is a 4xx Client 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, 404 means that the server cannot find the requested resource. The URL may be wrong, the resource may have been deleted, or it may never have existed.
