How to view Chrome's cached web page?

Type chrome://cache in the address bar to get a list of resources cached by Chrome.

Unfortunately, clicking on a resource shows a HEX+ASCII preview of its contents. In cases when the content is gzipped (archived) this preview cannot be read, unless processed with a tool that can decompress it.

You can use the online free tool I created: Google Chrome Cache Viewer. It's actually fairly easy to view the cache with this, even if the contents are zipped.

If you need something that doesn't necessarily exist in your browser cache, or say you want to see an older version, you should check out The Wayback Machine aka the Internet Archive. It has been a great source of help to me on numerous occasions. I use it for doing research into MMO history to understand old rule sets, patch notes, etc. Just punch in the url for the site and it'll show you the snapshots it has on record.
