HTTP Status Code
This module allows you to configure specific paths to return custom HTTP status codes, such as "410 Gone" for permanently removed content. This helps search engines understand that content is no longer available and should be removed from their indexes.
Adds the possibility to define a path which returns HTTP Status Code, like 410 for paths that are gone.
Use case
If you remove a page, the request for the path of the page normally then gives a 404 in the HTTP header - as it should. Google does not think this really means that the page is gone forever, just temporarily, so to make Google understand it is gone for real, you could set up the path for the path at /admin/config/http_status_code/http_status_entity and select that the path would throw a 410 Gone header. Then Google removes the path from the search index.
The module does not create pages, just manipulates the HTTP header.
