17: Why is my Wildcard rule not applying to top level WWW site?

The reason this happens is that "WWW" is specific, and since browsers in some cases strip, or mishandle "WWW" we treat the same way as to avoid any issues.

More Info:

Let’s say your goal is to have everyone use Internet Explorer as their default browser unless they are visiting Microsoft websites, and for Microsoft websites you want everyone to use Edge instead of IE.

To try to accomplish this you have created a Default Browser policy set to Internet Explorer, and a wildcard policy to redirect * to Edge, however, users report that they when they try to visit that the site still opens in Internet Explorer instead of Edge. The website however, opens correctly in Edge.

Assuming that the Browser Router Policy and prerequisites are all configured correctly, (i.e., the Default Browser policy, and/or other BR policies are working as expected) the reason this is happening is because wildcard rules like * ignore "www" and only apply to subdomains of the URL specified in the wildcard policy. The URL will be treated like and be opened in the default browser, Internet Explorer in this case, whereas subdomains like will be redirected to Edge as they match the wildcard policy. Said another way, wildcard rules like * apply to all subdomains of, EXCEPT www.

To workaround this issue you can either create a URL policy for or a wildcard policy for *Microsoft*. Either of the policies below will resolve this issue. Note: There is no "www" in the URL rule below.
