I ran into a login-related problem with NN4 about 6 years ago. This
was with an ASP site. The problem might be similar enough to suggest
somethig helpful:

I used a frameset that consisted of two frames. Everything was from
the same domain. On frame offered help links (that didn't require a
login). The other frame offered a login screen. Upon a successful
login, the login page was replaced by the applicaiton home page (in
the same frame). We were using the standard ASP Session to keep track
of the login.

This worked very well in IE and NN *** until *** we added SSL to
protect the login page. To do this, the login page url changed from
http://www.whatever.com/login.asp to https://www.whatever.com:443/login.asp.
The rest of the site url's remained the same. That broke the login
with NN4. It still worked fine with IE.

In NN4, the browser cookie was apparantly not getting set to record
the session id and thus the login state was lost. I experimented, but
was not able to come up with a simple solution. We ended up replacing
the frameset with a simple login page (no frameset). This allowed the
login to work in NN4 (cookie saved, even with SSL). Once logged in,
the user was redirected to the actual application, which then loaded
the frameset and two frames (help and application).

It looked like the problem was caused by bad vibes between NN4,
frames, SSL and cookies. I never found a smoking gun. I just changed
the design, which was not great to begin with.

BTW, I stopped using framesets almost 5 years ago. I stopped
supporting NN4 about 4 years ago. Haleluja!

I hope this helps.
