Instead of accessing the feed directly on the Web site, the reader passes through our system. If the feed is not currently in our cache, we query the feed on the Web site. Once we have cached the feed, we won’t fetch it again on the Web site until a certain period of time (30 minutes). Readers that connect to to get the feed will only receive the news that they haven’t seen yet (the user is authenticated by its IP address or by a GUID). So, for example, if the Web site hasn’t published news for 3 hours, readers won’t receive any news it has already received during that period. This optimises the reader’s and web site’s bandwidth. And since no installation is required by both parties, our solution can be used in less than 10 seconds!
