The server has effectively satisfied the request and that there is no extra content to send in the reaction payload body. 

Metadata in the reaction header fields allude to the target asset and its chose representation after the mentioned activity was applied. 

For instance, if a 204 status code is gotten in light of a PUT request and the reaction contains an ETag header field, at that point the PUT was effective and the ETag field-esteem contains the substance tag for the new representation of that target asset. 

The 204 reaction enables a server to show that the activity has been effectively applied to the objective asset, while inferring that the client specialist doesn’t have to navigate away from its current “report see” (assuming any). The server expects that the client specialist will give some sign of the accomplishment to its client, as per its very own interface, and apply any new or refreshed metadata in the reaction to its dynamic representation. 

For instance, a 204 status code is normally utilized with record altering interfaces compared to a “spare” activity, to such an extent that the report being spared stays accessible to the client for altering. It is additionally as often as possible utilized with interfaces that expect mechanized information moves to be predominant, for example, inside circulated rendition control frameworks. 

A 204 reaction is ended by the principal void line after the header fields since it can’t contain a message body. 

A 204 reaction is cacheable of course; i.e., except if generally showed by the technique definition or unequivocal reserve controls.
