IEBlog: IE8 and Reliability:
Of special interest to Vista users:
We have also added the internal capability to “hot swap” the process from
underneath a tab. Previously, Protected Mode worked on a /per-process/
basis. For example, say you add a website to your trusted sites in IE7. If
that site links to another site that is not in your trusted sites, it will
cause you to switch browser windows when you click the link.
We improved this in IE8 Beta 1 with LCIE when we split the frame from the
tabs. With the split we can create a new tab in the same window and switch
you to that tab as opposed to being “punted” to a new window.
Virtual tabs lets you navigate across Protected Mode in the /same tab/ since
we just switch the process under the tab to the correct integrity level.
This is really just “UI-sugar” – virtual tabs do not impact security or
protected mode in any way, other than to make it more convenient to
transition between protected mode on/off.
