Unless I am seriously misreading this data, it looks like the delay is
between eBay sending an ACK for the request and then sending the response.
This is odd behavior, but it probably isn't Squid's fault.

Can you duplicate this with other websites - not just eBay?

forwarded_for replaces the client IP with "unknown", whereas header_access
removes the header altogether. It might be worth trying header_access
instead.
