<!-- NAME="Polyserve" CAT="software" SUBCAT="NETWORK" -->
<STRONG><A HREF="http://www.polyserve.com/">Polyserve</A></STRONG> is a
vendor of a high-availability webserver monitoring and failover utility
for FreeBSD called Understudy. Understudy resides on two or more
webservers and monitors the health and responsiveness of websites. In
the event that Understudy detects a failure, it ?fails-over? requests
for the failed website to a backup server. Thus, people browsing the
website see no interruption or delay; from their standpoint the website
keeps right on working.<p>Understudy monitors IP services including HTTP,
SMTP, TCP and FTP. Upon detection of a failure, Understudy removes the
failed server from the cluster and fails-over to the secondary backup
host. Understudy then generates a network administrator notification
via email and/or page so that whatever problem caused the failover can
be remedied.<p>For more information, visit <A
