Actually you are right...It will only work on a specific domain. Our
institute has IEEE subscription...hence from the machines within the
institute, I can download the papers.
One of my friend suggested a way which is as follows...

   1. make sure that http_proxy is set to proper proxy in shell
   2. wget *"http://ieeexplore.ieee.org/**stamp/stamp.jsp?tp=&arnumber=**
   5173739&isnumber=5173690"* -O /tmp/ieee_paper.html
   3. wget `cat /tmp/ieee_paper.html | tr '\"' '\n' | grep '
   http://ieeexplore*.*ieee*.*org/stampPDF/getPDF*.*jsp'`  -O ieee_paper.pdf

With this I can now download the ultimate PDF file from IEEE.

But I was not able to download the mozilla exe from the dynamic link.
I would appreciate if anybody would suggest the way to look into  the souce
file of the intermediate html file and then how to figure out the final
command to download the ultimate file.
