One more thing.
The iSiloX documentation says "An off-site link is defined as a link to a target in a different domain."
In actuality, different servers in the
same domain are excluded when one excludes off-site links.
For example, I have a Weather URL which starts with
http://printer.wunderground.com, and if off-site links are excluded, then
http://radar.wunderground.com and
http://autobrand.wunderground.com are also excluded.
