RSS Output Feed
 

Hi I've done some searching and not found an answer to my questions.

I think I may have a problem with the RSS feed that is provided by vBulletin for other applications / sites to consume.
So for absolutely clarity.... http://yoursite/forums/external.php?type=RSS2

How does the updating of the RSS feed work?
Does it work by providing a real time list of posts each time the URL is accessed or is there a timer job?
