I wonder if know how i can download some files which will be downloaded after
some js event after page load completely. 
I know the dynamic locations of my interested files. But httrack can not find
them because they address will generat after page load completed. For example
httrack can find and download these files:
someweb.com/SOMEDYNAMICFOLDER/images/*.jpg
But can not track this file:
someweb.com/SOMEDYNAMICFOLDER/contents/*.gz
As you see SOMEDYNAMICFOLDER is same, but contents folder and files inside
that are not trackable. How i can download this dynamic folder and contents
inside?
