Secure webdav?

Hi!

For security reasons "some people" want to only use https for logged in and edit mode in Jahia.

I have succeded to help them by using java script in the login.jsp file and in common header jsp files which changes protocol if logged in or if they want to logg in.

Now they want to force or ensure https also if they use an external webdav client like windows file manager. Has anyone heard about such a requirement and how to solv the problem. It would be nice if it could be done by reconfigure jahias web.xml or tomcat.

They have to use IIS! ( This would not be any hard problem if they could use Apache Web Server)
