what is mod_jk parameter "connection_pool_timeout" in mod_proxy / mod_proxy_ajp / apache httpd?

[Arne Riecken]

Hello,

in the past I used mod_jk with workers with connection_pool_timeout=600 and
tomcat ajp connector with corresponding connectionTimeout=600000 as
recommended.

Now I additionally want to use mod_proxy_ajp with apache 2.2.9. Where in
apache httpd do I honour the tomcat connectionTimeout=600000 ?

Using apache2.2 prefork-mpm.

Thanks.
