I too am seeing this problem.  I am calling a PHP script that returns
an XML string.  However, it is always caching the last request results
- last request being one that passes the same URL and arguments.  To
get around some of this I have started adding an extra argument on the
URL that passes along the result of "Math.round()".  This ensures that
the URL changes.  This solved the problem - but I don't like it. 
Really seems like a hack.

I will look into the header, as was mentioned, but if anyone solves
this please let me know.  Thanks.
