Websites that should never trigger a browser switch.

Setting the policy controls the list of websites that will never cause a browser switch. Each item is treated as a rule. Those rules that match won't open an alternative browser. Unlike the BrowserSwitcherUrlList policy, rules apply to both directions. When the Internet Explorer® add-in is on, it also controls whether Internet Explorer® should open these URLs in Google Chrome.

Leaving the policy unset adds no websites to the list.

Note: Elements can also be added to this list through the BrowserSwitcherExternalGreylistUrl policy.

Example value:

ie.com
!open-in-chrome.ie.com
foobar.com/ie-only/
