1) A Mirror is not a copy, it is a static snapshot. Forms will not work. There
is not database.
2) Java is a program. HTT can not modify programs

> url <https://subscribe.csa.ca>
3) Clicking on that link forwards to 
<https://subscribe.csa.ca/irj/servlet/prt/portal/prtroot/pcd!3aportal_content!2fcsa.CSA!2fcsa.iViews!2fcsa.csa_i_gatewayAnonAccess?guest_user=subuser>
So you should have started there.
4) On the left is a log in form. You should have had HTT log in HTTrack Help:
Authentication
<http://httrack.kauler.com/help/Authentication>

5) HTT can not log in using a https link.
Can't be done.
