I tried this but it didn't work as it does with
"%{my-ecap-header}adapt::<last_h". I am not sure if "my-ecap-header" is a
really a header as I called it as I hand it over to squid as
libecap::NamedValueVisitor when visitEachOption() is called. I guess it is
an ecap option or ecap meta information rather than a header, right? I guess
when you talk about ecap headers you mean http headers set by the eCAP

Should the logging with %note and applying ACL also work with ecap meta
information and am I doing something wrong or is this not supported with
ecap meta information? In the latter case I guess I would have to change it
to a solution where the eCAP adapter sets a proper http header which can
then be logged as described above.

Source of confusion:
"adapt::<last_h	The header of the last ICAP response or meta-information
from the last eCAP transaction related to the HTTP transaction."
