You might have slightly misunderstood. I have a link for RSS feed. When user clicks on RSS feed, it gives the URL for the RSS feed, particularly for that user. URL should be of the form: server/cgi-bin/rss.pl?feed_id=ABCDEF123456787980". They can take this feed id and plugin into their favorite RSS reader. Now, I should be able to decode the feed_id on the backend, whenever they call and genrate live RSS feed for them.
