Java EE (Java Enterprise Edition) General Discussion

I am having an issue with XMLHttpRequest. The call to my servlet has one request param at the end of the URL. It seems to be calling my servlet just once per param value and caches the XML it returns. For example, if the param=1 it runs the servlet just fine. If the request is made again with param=1 it just spits out the same information as before, which should not be happening. What leads me to believe the servlet isn't running the second time is 1)that my System.out's will run the first time but not the second, and 2)my debugger will halt at a breakpoint the first time but not the second.

Is there something that needs to be set in my JavaScript that forces the request to actually be run every time? This seems very strange to me.
