Hello,

question about keepalive for mod_proxy (via ProxyPass directive) AJP
connections:

"This flag will tell the Operating System to send KEEP_ALIVE messages on
inactive connections (interval depends on global OS settings, generally
120ms)"
(http://httpd.apache.org/docs/2.2/mod/mod_proxy.html#proxypass)

A send keepalive message interval of 120ms seems very short for me.

On Linux there is a default time of 7200 s to wait on a idle tcp connection
and then send keepalive messages in an interval of 75 s, according to
http://tldp.org/HOWTO/TCP-Keepalive-HOWTO/usingkeepalive.html

Can someone please get this clearer?
