Suppose I wrote some code to generate an RSS for a web site. A few RSS readers subscribed to the RSS.

Suppose I updated the RSS generating code and now my RSS changed. The RSS subscribers though still display the "old" RSS since they didn't read the RSS again.

Now I wonder how to make the RSS subscribers "refresh" the RSS items. Can I add a tag/field to the RSS to make the subscribers read the old RSS items again ?

Your safest option is to make new entries with a new <guid>: https://stackoverflow.com/a/164595/989257. Also updating titles or content could make some readers consider the old entries as new/unread.

  • I am afraid that changing `guid` will make duplicates. Does it make sense ? – Michael Mar 02 '15 at 13:22
  • It probably will make duplicates, but It will also guarantee that rss readers see the items as new. Instead you could just try to update title and description tags. – janih Mar 02 '15 at 13:44
  • Ok, thanks. I am afraid the duplicates are even worse :( – Michael Mar 02 '15 at 13:45
