Disappearing Old Pages Question

[Outkast]

I was just, 1:55pm Friday April 11th 2003, looking in Google to see if my new website had shown up yet. I used allinurl: and it returned results. Good thing. Except for the fact that they were from an old folder structure I had used when I first built the site:
www.mysite.com/manufacturer/products/producttype/product.asp
I have since revised that to be:
www.mysite.com/manufacturer/producttype/product.asp

So, after seeing my results in Google I hurried over to my site and added the old folder structure back. I didnt delete what I have now I simply added the old structure back in. So you can get to the product.asp pages both ways. Well, I go back to Google and allinurl: now returns nothing.

What gives?

And should I worry about the old structure being indexed, did I over react?

Suggestion:

<?php
header("HTTP/1.1 301 Moved Permanently");
header("Location: [mysite.com...]
?>

Should have been placed in the old structure? You got duplicate content issues?

I have since added

Disallow: /manufacturer/products/

to my robots.txt file. I want the /manufacturer/ folder and all of its contents indexed but I also want the /products folder to show so I dont have 404's on my newly indexed site. In a month or so when the product pages go away and only the new pages are there I will delete the product folder all together. Right?
