HTTP response status code 410 Goneis a client error that is returned by the server to indicate that the requested resource is permanently unavailable. This is similar to 404 Not Found, although it more specifically indicates that it did exist, but is unavailable and this is expected to be permanent.
When the 410 Gone error message is received, the client knows that the address was valid at one point, but the resource no longer exists. This can be the message returned by the server after a resource, such as a document available as part of a limited-time offer, expires. If the server does not expect this to be permanent then another code, like 404 Not Found, can be used instead.
This status code is helpful for web maintenance and is specific enough that clients need to remove links to the resource.
Search engines like Google will not index a URL with 410 Gone response status, and consequently, URLs that have been indexed in the past but are now returning this HTTP status code will be removed from the search results.
In the example, the client requests a resource and the server responds with a 410 Gone because the promotion has ended and the content is no longer available.
