Thanks for this. Chrome extension can be found here. https://chromewebstore.google.com/detail/web-cache-viewer/pb...
Basically: 404 tells crawlers that the URL is invalid.
The HTTP server also has to return something,. It could simply return 0-length content and allow the browser to show its error page, but that wouldn't be "on brand."
