So, here's my inference about the Google 'cache' story: * These copies are made primarily to facilitate indexing and other access in support of Google Search. In this context, they are a classic cache: they are used as high performance, easily accessed copies of representations from the original URI. So, with that in mind, this is known as Google's "cached" copy of the representation. * Given that's there, it can be handy to let users see that "cached" copy, and for that purpose Google makes at available under a new and different URI, which is what you're discussing. That is indeed served from a link labeled "cached", but I think what's intended on careful reading is: "link to the copy that Google created for caching purposes in its search engine". Once accessed in this non-transparent way, it is indeed no longer being used as a classic cache. Noah
