copy https// with login

[vbsarea]

Good day. Have tried downloading one particular site with no luck.
1-All files use the https//
2-By using a form,one can login using a guest login that uses a javascript Postback method to get authenticated then uses a forwarding url to get user to good part of the site.


3-It appears to me, user stays logged in using cookies (.ASPXAUTH:,__utmc ,asp.net and so on)
4-all the copy software i use seem to copy the public files but once it is redirected to where the good stuff is you are sent back to the login page.


Is this site possible to download?
