Query strings. Its all about query strings.
It is a kinda hacky way of going about this – but basically the concept is you add a variable to your URL (the query string) that is different every time it is loaded (e.g., a math random function).
In my example, I am using SimplePie, a PHP RSS agregator class, to pull in my flickr photos.
$flickr->set_feed_url(array('http://api.flickr.com
/services/feeds/photos_public.gne?id=83039253@N00=
en-us&format=rss?'.rand(0,99)));
At the end of the URL you will notice ?'.rand(0,99). The ? is the beginning of the query string, and the “.” is concatenating a random number between 0 and 99 onto the end of the URL.
Hope this helps someone.
