I tried to use Httrack and Sitesucker to download the content of a login required website but the webpages it downloaded are all like login forms, register and seekpasswords.html, without the real content. The website is pretty much like treehouse or Udemy and I have bought a course on it but the course will expire next month so I was hoping to see if I can save the content before it vanishes(is it illegal? I don't know).
Both Httrack and Sitesucker didn't ask me about the login info though. Therefore, how can I download the content or it is just simply impossible?
Thanks!
