proxy_ajp behind a firewall

Under mod_jk a "best pratics" (10 minutes session timeout 4 example) was:

Adding the value connectionTimeout="600000" in the connector field in
server.xml
for example
<Connector port="8009" enableLookups="false" redirectPort="8443"
protocol="AJP/1.3"
connectionTimeout="600000"/>

And in workers.properties:



worker.node1.socket_timeout=10
#This value must equal server.xml's connectionTimeout of 10 minutes



Which parameters should I use with proxy_ajp?
I've found that:

mod_jk proxy_ajp

connect_timeout ping
socket_timeout timeout
timeout ttl

Is it Correct????
ProxySet balancer://ajpCluster stickysession=JSESSINID nofailover= ping=1
timeout=10 ttl=60
