> Some sites have a common starting page and then they have 
a
> separate site for each section/topic.
> Example: 
> The main site could be-
> <http://www.mainsite.com>
> And the other sites could be-
> <http://topic1.mainsite.com>
> <http://topic2.mainsite.com>
> .....
> <http://topicn.mainsite.com>
> The main page has URLs which take the reader to the other
> sites. The actual data comes from these 'subsidiary' 
sites.
