Hi. I am interested in how does Google Reader fetch old entries of a RSS feed? For example, when I subscribe Neowin.net, Google Reader can show me very old entries from Neowin.net. How does Google Reader fetch old entries, and is my main question is: Is there any way to do it besides caching?
Google good at fetching data and index them, so I guess Google can cache data from Neowin. Once people subscribe Neowin RSS feed in Google Reader, old entries and be retrived from Google's cache. But what if Google didn't cache a website and someone subscribed it in Google Reader?
Does specifications of RSS/ Atom specified how should old entries be fetched from server?
And, if any, could someone suggest me a RSS feed cache?
