"dst" requires a DNS lookup. This is a "slow" category ACL as we call it
in Squid.

tcp_outgoing_address is a "fast" category lookup. Which has no guarantee
of working when using "slow" category ACL types.

You need to get the "dst" lookup results cached in squid memory by an
earlier "slow" category lookup. http_access is good for this.

One http_access line which does the lookup (for example, the line which
permits that client access to the local_network area) will make the
address lookup work in most requests (emphasis on "most", no guarantees).
