Squid is a proxy. That means when a browser accesses a server ther are two
connections, not one. The first connection is from the browser to the
proxy. The second connection is from the proxy to the server.

If the packets headed for the server had the browser source address, the
server response would not be cached. The packets would not be sent to the
squid box but the browser so the squid software would never see the data
from the server.

There is an HTTP header that can include the browser's IP address and is
configurable in squid - see squid.conf cos I don't recall what it is.
