More correctly it is the direct endpoint of the client TCP connection.
Not the chain of multiple TCP connections, which may include NAT or
other protocol translations between Squid and a user.

The easiest approach I think would be to add a javascript snippet in
place of the %i code that locates the users IP address and displays it
to them.

This (2) is actually a lot more privacy-friendly for end users. Since
you/Squid dont have to go digging into information about the internal
network structure of their ISP just to display it.

The requirement that Squid error pages be static HTML only applies to
how they are generated as responses at the server (Squid) end. The page
itself can reference external resources, or contains scripts the client
(browser) end runs.

Not a problem. Quite good compared to some.
