Yahoo Hit a Page that has Never Existed

What is Yahoo up to?

[jake66]

yahoo just hit a page (that has never existed) on my site:
/?S=A

and of course, this produced a 200/ok response.

is there any way to push a 404 when yahoo looks at this url?

I got a few requests for similar pages today when using 3rd party software to create a G Sitemap, so I don't think it's strictly a Yahoo thing.

May be an external Link pointing to your Site with that, and yahoo is just following the link

Can you track if the hit had a referer or not?

Can you track if the hit had a referer or not?

yahoo never outputs a referral string, so no

i don't think anyone would link to something like that, as the page has never existed.

i would hope a competitor wouldn't be able to sabotage my ranks by linking to such a filename..

Is it that the page doesn't exist or an exsiting page was passed a funny query string that resulted in no content being displayed becuase the query string variable value or the variable name itsefl was wrong?

[jake66]

it was definately, 100% a page that has never existed... but because of the /? in the url, it produces a 200/ok response.
