Reading about RSS leads to many false-informations. I am not quite sure how RSS works. So I have some questions and I hope you dont answer using links-only. There is always another link that claims your link is wrong.
- If I subscribe to a RSS-Feed the first time, are the feeds from the last 30 years downloaded as a bulk-response may have Gigabytes of data?
- Are following requests to a already subscribed RSS-Feed updates to the previous subscription? If yes, how does the server know what messages are already transported to the "client"?
- How often are RSS-Feeds downloaded?
