I would like to make a site available for off-line browsing but it:

1) Uses frames
2) Requires a login through a javascript form with "sign in" button that
requires username and password.

I have my username:password and want to extract specific data from a search
option after logging in.

Can anyone please advise the method of doing this?
NB: If i use "capture URL" it does not secure the URL - I presume because of
the frames or script approach.

Any help much appreciated and thank you for an excellent tool.
