@juanduke, @Paolo,
Thanks for sharing your time & ideas.
I successfully implemented your idea by juanduke.
The url -- http://www.ajaxload.info/ is excellent.
Regarding Paolo's code, I need to re-structure my code somewhat (which
I will definitely do).
Then I will implement the idea.
In case of any query, I'll post it here.
Thanks again.
