438856 automatically grab google cache version

I need a tool that will help me rebuild some of my sites based on what's in the current Google cache. I want a tool built in php/mysql that will go out and look for all the occurrences of a site in Google's cache and then store the content of those pages in a database. Then, when that page is visited in the site, it pulls that information from the database. This should use an .htaccess file that then passes that requested page to php to look it up in the database. So assume you're starting with a blank site that has lost all of its files. I want to be able to upload an [login to view URL] file, an .htaccess file and then configure the [login to view URL] file to point to a mysql database. Then there could be an additional file, like [login to view URL] that I would go to and hit "go" and then it would pull all of the files from google's cache. The site could have 100 pages indexed or it might have 10,000 ... the tool should be able to handle both (it would obviously take longer the more files that are indexed.)
