That doesn't work for me. The "ErrorDocument 503" declaration in
httpd.conf only works when Tomcat is completely down, not when a
single webapp is stopped or reloading. As long as Tomcat is running,
you'll get Tomcat's error pages. And, you can't override this in
Tomcat's conf/web.xml, only in each webapp's web.xml, which makes it
impossible to customize the 503 page. :-(
(I've tested all this with Tomcat 5.5, Apache web server 2.0, JK 1.2.
Maybe it's different with Tomcat 6 or Apache 2.2.)
