No - httrack can only retreive data, not push it (this 
could be done using HTTP through PUT, but this feature is 
generally NOT supported by servers for security reasons). 

Can't you push it using ftp or rsync? rsync would be the 
best solution IMHO, because it limits the bandwidth usage 
by calculating differences between two structures and 
compressing them.

rsync is quite easy to use:

rsync -avz --delete MyFolder 
root@remoteaddress:remotedirectory

And you can use it on Linux/Un*x systems, and Windows using 
cygwin (http://www.cygwin.com/ - including the ssh daemon)
