HTTP 100 Continue vs 203 Non-Authoritative Information
HTTP 100 (Continue) is a 1xx Informational response, while 203 (Non-Authoritative Information) 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, 203 means that the response payload has been modified by a transforming proxy from the origin server's 200 response.
