This isn't yet possible

> Does httrack for windows support .httrackrc ?
it supports httrackrc (without leading ".")

No - totally different one - example:
set sockets 4
set near on
deny ads*
allow *.gif
allow *.jpg
allow *.css
allow *.js
allow *.png

To summarize, you have three keywords: allow/deny for scan 
files, and set <name> <value> to set options (option names 
are listed with httrack --help between parenthesis)
