There are no links on the changelog page for these and I was hoping to see
some details about why this option was added.
"Optionally trigger authentication instead of denial in RemoteAddrValve and
RemoteHostValve"

http://tomcat.apache.org/tomcat-8.0-doc/config/valve.html#Remote_Address_Filter
"The behavior when a request is refused can be changed to not deny but
instead set an invalid authentication header"

Example #3
"To allow unrestricted access to port 8009, but trigger basic
authentication if the application is accessed on another port:"

I'm trying to understand this kind of setup.

If an IP has been allowed to pass through via a Filter to a restricted
resource, wouldn't the user get the container configured authentication
dialog anyway?
