Alternative to error 404 during redeploiement?

["Henri Dupre" <henri.dupre (at) gmail.com>]

To monitor tomcat I current have a script in a crontab that checks an URL
every 5 minutes.
This works quite well except during the redeploiement... Tomcat throws an
error 404 but the detailed message says that the application is not
available.
Would there be a way to throw a different error code during redeploiment so
that my script won't restart tomcat?
