Keep-Alive for servlet
The documentation says about "Keep Alive Timeout" that it applies to persistent connections and about persistent connections that they only apply to "FastCGI external application".
When configuring a servlet external app, the "Keep Alive Timeout" is configurable through the management interface but its value is not applied to ajp connection (they time out after a few seconds, whatever the value is). Perhaps this is on the tomcat side, but it does not look there is some config option about keepalive for ajp in the servlet server.
Any hint about the way it really works in 2.2.2 appreciated.
