[Xerte] Re: Standard method of preventing caching?

Yep, my poor english and waffling masked that I said that in my original reply - look in modules/Xerte/play.php and preview.php - examples in there. I think the wizard has examples in it as well of loading files to avoid the cache.

url = 'http://blah.com?' + new Date().getTime();
makes a unique URL to prevent caching.

Thnx, I'll give it a whirl.

I vaguely remember the old pragma/no-cache and querystring tricks, just wasn't sure where to add them to force as many objects to reload as possible.

You think refreshing the swf will reload any of the called files?
Or shall I need to add random strings to all external calls (which is pretty much everything Xerte displays;-)).

Someone must have run across caching of external text/xml files in the past?
