Dynamic content and cache


I am working on a active desktop at the moment which pulls dynamic content. Pulling the content is not a problem, but when I try and refresh, the results are the same. This is what am using as per another thread i found.

[AS]on (release) { rn = Math.round(Math.random()*1000000); loadVariablesNum(“http://someserver/file.asp?reload=”+rn, 0);{[/AS]

As I said the results stay the same
Any ideas?
