Bizarre Google Result, what is this leak about?

[Thaddeus]

I had a page like this:

www.domain.com/money_page.htm

I put a slightly different copy of it up at

www.domain.com/sub/money_page.htm

and did a Redirect /money_page.htm www.domain.com/sub/money_page.htm in my .htaccess

One month later I replaced that with a

Redirect 301 /money_page.htm www.domain.com/sub/money_page.htm

A week later if I google the old page www.domain.com/money_page.htm I get three results for that page. Which is not good because I want them to be gone. (Clicking on the search results takes me to the new page, so it's not too bad. Is it?)

And if I google the new page www.domain.com/sub/money_page.htm I get told that search does not match any documents. Which is really not good :-)

But I noticed that if I make a type and google www.domain.com/sub/money-page.htm I get told that there is a similar page at www.domain.com/sub/money_page.htm so google obviously knows about the new page, and it's leaking out at this point.

Does anyone know what Google is up to? Duplicate content problem?

And what I can do to get the right result, which is the old page gone and the new sub page showing up?

Thanks everyone,

T
