The HTTP204 No Contentsuccessful response status code indicates that a request has succeeded, but the client doesn't need to navigate away from its current page.A204 response is cacheable by default, and anETag header is included in such cases.

A204 No Content in response to these request methods has the following meaning and results:

• DELETE: The action was successful, and no further information needs to be supplied.
• PUT: The action was successful, and theETag value contains the entity tag for the new representation of that target resource.

A204 response can be used when implementing "save and continue editing" functionality for applications like wiki sites.In this case, aPUT request could be used to save the page contents, and a204 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 theContent-Length header (browsers may reject responses that include content).
