204 No Content

The HTTP 204 No Content successful response status code indicates that a request has succeeded, but the client doesn't need to navigate away from its current page. A 204 response is cacheable by default, and an ETag header is included in such cases.

A 204 No Content in response to these request methods has the following meaning and results:

A 204 response can be used when implementing "save and continue editing" functionality for applications like wiki sites. In this case, a PUT request could be used to save the page contents, and a 204 No Content response indicates to the browser that the editor should not be replaced by other content.

Note that the response must not include any content or the Content-Length header (browsers may reject responses that include content).

In this example, the client sends a request to delete an image using the DELETE method. The request includes an Authorization header with a token to authenticate the request:

DELETE /image/123 HTTP/1.1
Host: example.com
Authorization: Bearer 1234abcd

After successfully deleting the image, the server responds with a 204 response with no body, indicating no further information needs to be sent to the client.
