This function is not yet in mainline Squid, but can be found in the rproxy 
patch at the location above..

Please note that there are perfectly valid situations where a client may 
change source IP address in the middle of a session. You can not assume 
the source IP is the clients IP. The client may be connecting to your site 
via a mesh of cache servers, and different requests during the same 
session may travel different paths in this cache mesh.

One simple example is a company having two cache servers in a load 
balanced manner. Another example is companies having more than two cache 
servers or peering with other cache servers.
