[http::]>ha logs request headers received by Squid and adapted by
ICAP/eCAP. It does not log request headers sent by Squid. There is
currently no logformat code to log the latter.

If you want to log outgoing Via, your options include:

1) add a logformat code to log outgoing request headers (requires
development);

2) use "note" directive and %note logformat code to log mypersonalvalue
when needed (requires Squid trunk?)

3) move Via manipulation to ICAP/eCAP while disabling Squid's Via
generation (requires writing or adjusting an adaptation service).

HTH,

Alex.
