In my main movie I am loading external swf files. The proplem is that these files are cached so when they load the updates aren’t shown. I’ve read some stuff about loading vars or xml with a random function to prevent it from caching, can that work with swf files? Maybe something like:

loadMovie (“news.swf?=”+random(1000),\_root.dropPage\_mc);

I’ve placed the meta tags in the main html to stop that from caching; which doesn’t really work. Could the same be applied in the html? Or maybe a php function when loading the main flash movie?

The files that are loaded are only a few kb so I’m not worried about the user having to load the files everytime.

Thanks
