<br><font size=2 face="sans-serif">Greg,</font>
<br><font size=2 face="sans-serif">For the Library Servers, here is an
example of using "Ultra Monkey" for a load-balanced clustered
Apache system:</font>
<br>
<br><font size=2 face="sans-serif">http://www.howtoforge.com/high_availability_loadbalanced_apache_cluster</font>
<br>
<br><font size=2 face="sans-serif">Basically, there are two "load
balancers" and they share a Virtual IP address (VIPA), so that all
of Nepal goes to this virtual IP, and it </font>
<br><font size=2 face="sans-serif">will get picked up by either load balancer.
Then the load balancer sends the data to one or the other of the
two Library Servers.</font>
<br>
<br><font size=2 face="sans-serif">The advantage is that you can lose either
of the load balancers, and either of the Library servers, and still have
a running system.</font>
<br>
<br><font size=2 face="sans-serif">BTW, this is how all the major websites
(CNN.com, etc.) do it, except they have perhaps 20 "Library Servers"
sharing the load.</font>
