Users are encouraged to use more than one URL Rotator. To achieve a finer level of control, use nested rotators. For
example, create a "master" rotator. We'll call our master rotator 'freerotator'. We'll also create three other rotators,
called 'freerotator-group1', 'freerotator-group2' and 'freerotator-group3'. We'll populate the three latter rotators
with URLs appropriate for the appropriate group. Our "master" rotator will hold the URLs to these other rotators.
Using the weighting method mentioned in the first section of this page, we can now duplicate a group rotator URL in our master rotator to give it more weight. For example, let's say we want group 1 URL's to show up 50% of the time, with the remaining hits going to groups 2 and 3. Our "master' rotator URL list would look like this:
When a hit comes in to the "master" rotator (http://www.freerotator.net/cgi-bin/freerotator), it will be redirected to one
of the URLs contained in it's URL list, which are all subsequent rotators. This will allow you to modify each group
of URLs individually, or change the weights for each group from a central rotator.
