   Hi Henrik,

    As a workaround, i have already done that, thanks for your tip.

    The interesting part is that i'm actually migrating from 2.5
directly to 3.0, and that exact scenario works just fine on 2.5-Stable14
! Squid 2.5 Stable 14 handles this scenario with no problems at all,
even intercepting a request to its own ip address.
