I see this config option in 3.2, but searching for this string (or

what does this option do?

"Enable forw/via database" :)
The forw/via database stores a copy of every unique Via: and
X-Forwarded-For: header which passes through Squid, along with a
count of how many time it was seen. This gets reset/emptied on log
rotate.
The lists are viewable with the via_headers and forw_headers cache
manager reports. Current squid do not use the DB for anything.
thanks, where should I have looked to find this in the
documentation/wiki?
I don't think it is documented. I had to read the code to figure out
what was using the configure option.

To be honest I've a mind to propose removing it entirely.
It does a lot of processing just to figure out a few stats that a
custom logformat and log processor could do better.
The only reason it has not already been proposed for complete removal
is that 3.2+ may need to use the Via: part of the DB to optimize
expect-100 handling.
