HTTP 100 Continue vs 204 No Content
HTTP 100 (Continue) is a 1xx Informational response, while 204 (No 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, 204 means that the server successfully processed the request but is not returning any content. Common for DELETE operations and form submissions that don't need a response body.
