HTTP 100 Continue vs 413 Content Too Large

HTTP 100 (Continue) is a 1xx Informational response, while 413 (Content Too Large) 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, 413 means that the request payload exceeds the server's size limit.
