Need help understanding support for Unix Domain Sockets in Tomcat 7.0.x

[Srinivasan Raman]

Hello folks,
In one use-case, for performance reasons, I wold like to explore the option of 
connecting from a in-house software load balancer running in a VM running Linux 
to a Tomcat instance running in the same VM using Unix Domain sockets.
Googling for this brought up some mention of Unix Domain Sockets as part of 
APR, AJP etc., but I could not locate any concrete examples of how this can be 
done.
Appreciate if anyone that has information this can point me in the right 
direction.
Thank you,
