When an article or comments are deleted, it can be useful to look at the Google web cache to retrieve it. However, my understanding is that the Google web cache might likely change in the future. I can use The Wayback Machine to save a page as it currently is - but I can't save the web cache view, due to robots.txt.
Is there a way to save, on The Wayback Machine or any other reputable online archive tool, the Google web cache as it currently is?
