I believe he means don't mix encrypted and unencrypted
content in the same security domain.

Some folks take images and other high-overhead items
and *do not* encrypt them for performance reasons, but
keep them in the same FQDN/security zone/domain
e.g.--www.domain.com/

Problem is, if your session token is a cookie, or
anything else the browser automagically coughs up,
then a call to:

http://www.domain.com/non-SSL-speedy-content

Will potentially pass sensitive info in the clear,
like the user session token if token=cookie.

Marking cookies =secure means that the browser
shouldn't pass them in clear if a mistake like
this is made, but I haven't tested that on anything
but IE.
