How Do I Fetch All Old Items on an RSS Feed?

Question

I\'ve been experimenting with writing my own RSS reader. I can handle the \"parse XML\" bit. The thing I\'m getting stuck on is \"How do I fetch older posts?\"

Answer 1

RSS/Atom feeds does not allow for historic information to be retrieved. It is up to the publisher of the feed to provide it if they want such as in the blogger or wordpress examples you gave above.

The only reason that Google Reader has more information is that it remembered it from when it came up the first time.

There is some information on something like this talked about as an extension to the ATOM protocol, but I don't know if it is actually implemented anywhere.
