Ever do something really stupid while making changes to a website and wish that you could step back in time and take a look at it the way it appeared yesterday … or more importantly take a look at the HTML before you hosed it up?

Well, luckily Google keeps a copy of every page it crawls. To see a cached page of your web site use this url:

http://webcache.googleusercontent.com/search?q=cache:URL

For instance, the cached version of the home page of this web site could be retreived as such:

http://webcache.googleusercontent.com/search?q=cache:http://mungomash.com

But, don’t wait too long. Eventually, Google will crawl your new hosed up version :)
