Does Jeeves understand what 404 means?

Does Jeeves ever give up on pages that don't exist anymore? I mean, c'mon!, it's been more than a year!

It's really just a rhetorical question now - Jeeves has been banned and I don't care about the loss in traffic.

That bald, old wanker has less wits than a drunken Man U hooligan...

Ahhh, I feel a bit better now!

Maybe Jeeves *does* understand what a 404-Not Found means... It means that the server can't find the file right now. The semantics of 404 imply no other meaning, so it doesn't mean the file was or was not intentionally removed, and it doesn't mean the file won't be restored 5 minutes from now -- or never. It just means the server can't find it.

However, Jeeves apparently does not understand what a 410-Gone response means. It takes them about a year to get that one right, IIRC.

My intent here is not to be picky, but just to highlight that the correct response for a file that was intentionally removed and is being requested via HTTP/1.1 [w3.org] is a 410-Gone. The earlier HTTP/1.0 does not define 410-Gone, leaving only the ambiguous 404 response... Which is how we (and Jeeves) got into this mess in the first place.

Yes, you are correct, and I don't consider it to be picky to point out the differences between a 404 and 410 response. (Coincidentally, I just re-read what RFC2616 had to say about those earlier today as I scrolled my way down to read up on 502 Bad Gateway - darn corporate proxy servers!)

I think I'm guilty of expecting bots to understand that when I serve a 404 that means the resource is gone, due to the poor implementation (on the SEs' side) of the 410 response. IIRC, only Google deals with it properly, but I shouldn't be quoted on that!

no they don't. I have pages there from ages ago and two dupes, one from that 1bu chinese site, and one from a domain which I know it was 301d.

I have across some 404s in jeeves before, pages containing "404" should not be listed for just that reason.
