Isn't there supposed to be a check for this? There is, but it is somewhat sensitive to what sites call themselves, which may account for this. If your neighbors' news systems know your site as "frobozz" but your software puts "frobozz.edu" in the Path line of articles you receive, your neighbors will happily keep on sending you articles that have already passed through your site once. It is fairly important that a site be known by one and only one name for news purposes. -- TCP/IP: handling tomorrow's loads today| Henry Spencer at U of Toronto Zoology OSI: handling yesterday's loads someday| henry@zoo.toronto.edu utzoo!henry

But couldn't frobozz itself ignore articles where frobozz is already
mentioned in the Path line?

It could, although at the moment C News doesn't; it didn't seem necessary. This is being re-thought. -- TCP/IP: handling tomorrow's loads today| Henry Spencer at U of Toronto Zoology OSI: handling yesterday's loads someday| henry@zoo.toronto.edu utzoo!henry

>But couldn't frobozz itself ignore articles where frobozz is already >mentioned in the Path line? I'd rather it didn't. You lose the chance of seeing forgeries that claim to have passed through your site. If frobozz gets an article with "frobozz" in the Path, then either it's already in the history, it's *really old* news, or it's a forgery. *Really old* news is better handled some other way. -- Felix Lee flee@cs.psu.edu
