Everthing is writen in php and i have create my own cms to update content and control services that site offers.
My idea is to add an item in rss when an article is been published. I think i have figure out a way to begin implement rss to my site, by creating the xml files per category with only the first basic structure and just the last 2 articles for every category.
Then upload them to the server and start fill them dynamically. I have set a limit to 10 items per category and when an rss has 10 items and a new article needs to be inserted, the oldest one will be removed.
An other question i have is if a user subscribe to an rss, lets say just with firefox, how and when firefox will inform the user for a new update?
