worker redirect problems

[Paolo Santarsiero]

Hi, in my cluster I have many tomcat enable and two tomcat in sleeping, all
in load balancing. The "sleepers"  start only when one or more active tomcat
go down, managing thier sessions. In order to do this I use
worker.tomcatActive.redirect=tomcatSleeper for active tomcat and
worker.tomcatSleeper.activation=disabled for disable tomcat. All works fine
when a tomcat go down but doesn't work when I stop a single application from
manger. Here browser shows me a 404 and the sleeper doesn't go in active
mode. Which may be the problem?
