Hi Amos.
Understood... thanks.
Then I think the names of the flags are a bit misleading:
they all end with "_hash", even if mask assignment is used.
Also, with respect to that fixed mask, 0x1741 .... I know that is the
default value, but it then means that there is no way to use a different
mask.
If the number of cache-engines is low, one could think on having a mask
of just 1 or 2 bits for instance, so that the processing time at the
router is minimized.
What do you think?
Thanks.

Could you please be more specific?
I cannot find any wccp-related directive in Squid named IIRC or similar.
IIRC = "If I Recall Correctly".
I am basing my answer on code knowledge I gained a year or two back.
Just re-checked the code and confirmed. The flag names on
wccp2_service_info are the same for both hash and mask methods. What
they do is different and hard-coded into Squid.
For mask assignment the static mask of 0x00001741 is sent from Squid for
each of the fields you configure a flag for.

Examples of what you need for your earlier requested config (Sorry about
the line wrap):
wccp2_service_info 80 protocol=tcp flags=src_ip_hash
priority=240 ports=80
with mask assignment method sets the mask to be 0x1741 on the packet
src-IP when protocol is TCP and dst-port 80.
wccp2_service_info 90 protocol=tcp flags=dst_ip_hash
priority=240 ports=80
with mask assignment method sets the mask to be 0x1741 on the packet
dst-IP when protocol is TCP and dst-port 80.
