Luckily the capture URL did work, but what a trouble! If there was an internal
mini-browser it would significantly enhance HTTRack's ability to do this? I
think Black Widow works exactly like this for cookie-protected sites, first
you log in with its own minibrowser, then start the scan, noproblemo.

Because the capture URL will not work, if the login would be in several
stages, right? first ask username, then new html page ask password, HTTRack
doesn't know what to do? But if it had an internalmini-browser it could
capture whatever sites with whatever forms of protection, because HTTRack
would be the browser and be inside already!!
