Besides the headers required by the ICAP protocol, Squid can be
configured to send ICAP [extension] headers defined by the following
configuration directives:

  * adaptation_meta
  * adaptation_send_client_ip
  * adaptation_send_username
  * adaptation_masterx_shared_names

IIRC, modern Squids support logformat %codes in "quoted" ICAP header
values configured using the adaptation_meta directive, but the
documentation does not mention that fact (a documentation bug).


HTH,
