When Facebook drives traffic to an app, they often append &ref=whatever to the query string. This is useful for figuring out which integration points are working or not. I've figured out what some of these mean. For example:

ref=bookmarks - the user clicked on a bookmark.

ref=game_my_recent - the user clicked on the upper portion of the games dashboard.

Does anyone know what "ref=ts" means? It accounts for a ton of traffic. I've viewed source on pages all over common FB pages and cannot find a match for ant piece of content generated by any of my apps.

Same question, posted by me on the FB DEV FORUM: http://forum.developers.facebook.com/viewtopic.php?id=54866

I'm thinking I'll get better answers here ;)

Thanks people,

Jose
