You don't need to, the URL always starts out the same. If you go to google.com, and in the search box type in cache:ebay.com it will show you the 'cache' that google has of that website. No matter what website you put in, when you click the 'search' button, the URL address in your browser will start with http://74.125.95.132/search?hl=en&q=cache which is the URL for google searches. In the case of ebay.com, the URL is http://74.125.95.132/search?hl=en&q=cache%3Aebay.com&btnG=Search Note that the 'ebay.com' occurs after the question mark in the URL. Anything after the question mark (in any URL) is called the 'variables' and the reason this is a loophole for most filters is that most filters do not look at the variables.
