[Zope] 404 on "/manage" frames with mod_rewrite

Hi folks, I managed to find some good information on putting zope behind apache and using mod_rewrite. This appears to be working fine as long as I'm using a non-framed page (and it works with SSL too). However, when I try to access the site using https://mysite.com/some_zope_page it works, but if I try https://mysite.com/zp/manage, I'm prompted for my zope admin credentials, and once I submit the credentials the framed portions are all 404d. When I check the url for one of the framed pages it looks like this: http://mysite.com:443/manage_workspace. Any idea if it is something I have misconfigured in Apache or is it something I've misconfiguration in Zope? Bernard
