Question: I visited a webpage but now the webpage has been removed or the server is down. I assume that Chrome has cached a version of this webpage. If so, how can I view this webpage?

Answer: 
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.
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](https://archive.org/web/) 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.
