How does java web start cache parameters?

I am running a java web start app, and I am passing a parameter to the app from my jnlp file. My jnlp file is generated by php so my code looks something like this:
$gProductID = intval($_COOKIE["productRef"]);
<jnlp ... >
<application-desc main-class="reading.RGReading">
This works just fine the first time I run it, but it seems from then on, it will run as though the same value I originally sent, is sent every time. In other word, if I run with value 14 the first time, it will run every time as though value 14 was sent, even though I have $gProductID set to another value like 16.
I found if I delete the sun java deployment cache, it lets me rerun with a new value. Obviously I can't expect users to clear their caches all the time so a solution is needed. Does this have to do with the cache? If so, how do I get around it? Or something else causing the problem?
Thanks for helping!

try adding a dummy parameter to the jnlp request or disable caching of the jnlp on your server


timestamp makes a good dummy var

Thanks for the help. I'm investing if version is an issue. According to sun forums, it seems that browser caching may also be an issue to contend with. See http://forum.java.sun.com/thread.jspa?threadID=592749&messageID=3662528
