I was wondering if there is anyway to view an older cached version of a website than the one that shows up when you click cached on google.
Use the wayback machine. It is on Archive.org, http://archive.org/web/web.php. Archive.org has been crawling the web for a long time, saving pages.
In the top center box is the Wayback machine. Put the URL you want to view there (note the Http:// is already there) and if it has taken any snapshots, you will see a timeline at the top of the page showing you what dates it has.
I find about 3/4s of the webpages I'm looking for.
It's a very useful site!
