This is a common technique to throw off caching mechanisms.
The "p" parameter is a dummy parameter that gets a random value so that when
the submission is made, since

Hello,
See if this helps you.
I have a form with remote DIV which displays chart after user clicks on

Trick here is to generate chart object, store it in session and display it
in separate JSP. Remove the form part if you want to display just the
dynamic-DIV using Chart image.

My question is whether there is a way I can manually force the img tag to
invoke the action itself.
Thanks for any input
