Good day Annajiat Alim Rasel, thank you for your help...

I am glad to hear you say: "I am getting curious to make it
work..."

<http://www.httrack.com/html/step9_opt11.html> is in case ".asp pages are in
fact HTML pages"
so you can tell .extension to be HTML but not SHTML

The only way I can get it to somewhat work is via
<http://www.httrack.com/html/step9_opt5.html> > OPTIONS and
%h%p/%n%q.shtml
BUT the problems is that ALL files (images...) get .shtml extension :(

I am testing on any site like <http://www.vtc.com/>

I really do not want to make a script which I am sure will run into exceptions
time and time again, if it might be a simple "html" to "shtml" change at the
core of the application... but perhaps it is somehow accessible via some
options or via minor edit of binary file...

Any help is very much appreciated...
Thank you all...
