The hand-rolled CMS I have for entering news on my site has a re-edit page previously pointed to an old format for the URLS (which I just corrected)
However, I just noticed today that I have about 98 pages in the index that are using the old news URL.
Here's the issue:
1) the old url gets redirected to the new one by a 301. Http live headers shows the redirection
2) the edit area is in an area of the site that bots should not be crawling due to a robots.txt directive.
How is google storing the old url style? Why would it be ignoring the redirect and storing the old version?
