This is not necessarily true. If your session information persists as a cookie
and your servers support fail over technology then the user may experience a
little hiccup, but they won't loose their session. If you're interested in this
sort of ultra-reliable web server technology check out the ART Technology
Group's Dynamo server suite. Sun and MySun all run on Dynamo servers using
load-balancing and fail over technology giving us 24/7 availability.
The ART Techonology group can be found at: http://www.atg.com
Sun and MySun are located at: http://www.sun.com and http://www.sun.com/mysun
