In the first diagram, notice that there are three Web server computers, each
with its own Autodesk MapGuide Server. Each contains different data. In this
case, requests are distributed among the servers based solely on which data is
requested; if repeated requests are made for the same data, only the server
containing that data will process the requests. To make this model work, you
must plan the placement of your data carefully so that requests are distrib-
uted equally among the servers.
