Container's AJP13 handler does not setTcpNoDelay on accept

Thanks Henri.

Certainly, Mac OS X's IP stack can be further optimized so that the
interaction between Nagle and delayed ack can be minimized (Linux, which I have tested, didn't
suffer as much).
But I hope it doesn't take away the fact that ajp13 protocol lends itself
to be a good candidate for turning on TCP_NODELAY, by default.

Anyway, I took your advice and tried to add tcpnoDelay to true.
Unfortunately, it didn't work. I tried both with 
CoyoteConnector+JKCoyoteHandler and simply Ajp13Connector. Looking at the 
source codes, there is nowhere in either ChannelSocket.java nor Ajp13.java
that turns TCP_NODELAY on/off. As well, the docs didn't mention that
"tcpnoDelay" is a valid attribute in the XML element <Connector>.

Here's part of the server.xml

<!-- Define a Coyote/JK2 AJP 1.3 Connector on port 8009 -->
    <Connector className="org.apache.coyote.tomcat4.CoyoteConnector"             
 port="8009" minProcessors="5" maxProcessors="75"              
 enableLookups="true" redirectPort="8443"
 acceptCount="10" debug="0" connectionTimeout="20000"               
 tcpNoDelay="true"               useURIValidationHack="false"
protocolHandlerClassName="org.apache.jk.server.JkCoyoteHandler"/>


<!-- Define an AJP 1.3 Connector on port 8009 -->
<!-- I tried this as well
    <Connector className="org.apache.ajp.tomcat4.Ajp13Connector"             port="8009"
minProcessors="5" maxProcessors="75"              
acceptCount="10" debug="0" tcpnoDelay="true" />
