Now on html page, I have two buttons to show/hide the div element. After I hide and show the div, the pdf is downloaded again although Firefox already cached it (I viewed Firefox's cached by using about:cache).
This problem doesn't happen with IE browser. I tried to search information about this problem but no luck. Does anyone face this problem before? I used FF6 and Adobe PDF reader 10.
Here is what I captured from Firebug
