Jk-Coyote should probably match the Apache2 defaults, since with the
pre-fork MPM, connections are 1-1 with Apache2 children.

No keepalive sounds like a bad idea: You are going to free-up connections
much faster if you get the image files out the pipe then if the browser is
immediately turning around and re-establishing a connection. It might also
be a good idea if there was an option to disable this, for the few cases
where you care more about the the connected user's experience then the
new-connection speed (Applet classloading comes to mind).
