ASP 1.0 site, pointing to ASP 2.0 site. SSL and authenticationobsticles??

RE: ASP 1.0 site, pointing to ASP 2.0 site. SSL and authentication
obsticles??

First off, Is there any way to simple development on an asp.net 1.0
site using vs 2005, if you don't have the sources (*.vb ), and don't
have the project either? Presuming not.

as an alternative..

Say that old ASP.NET 1.0 site/server has SSL, and I already have some
pages built in 2.0 on another server. That 1.0 site has the security
authentication pages (apparently form and db authentication), I want
to have my new pages seen and secured by that old site. I can build an
iframe pointing to my site pages, but will I still fall under SSL?
also, for authentication, presuming that page with iframe already
confirmed I am authenticated and can't be called directly from the
outside.. is this a security model that will work?

I undertand that Ideally I find the sources and take the whole site to
2.0. However, the site appears to be a vendor product and I don't
think sources are accessable.

Any suggestions?

Thanks for any help or information.
