HTTP 100 Continue vs 205 Reset Content
HTTP 100 (Continue) is a 1xx Informational response, while 205 (Reset Content) 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, 205 means that the server fulfilled the request and the client should reset the document view (e.g., clear a form).
