That's right - mainly because httrack *needs* original HTML data to rebuild
the internal filestructure (links are rewritten so that they can work
flawlessly when browsing offline with a regular browser).

There is no workaround yet for html data (httrack makes its best to catch
existing non-html data, but html data is not possible)
