205 Reset Content
Meaning
The server successfully processed the request, and is not returning content, but it expects the client to reset the document view that sent the request.
When to Use
When you want the client to clear form input or reset the UI after a successful action, without returning content.
Example
After a form submission that clears data, the server returns 205 Reset Content to instruct the client to reset the form view.
When Not to Use
Do not use if the client should not reset its view or if you need to return content (use 204 for no content without requiring a reset).
