Squid cannot modify header by adding httponly flag to an existing cookie value, but you can use an eCAP adapter (Squid v3 only) or an ICAP service (heavy) to do that. For more info, see http://wiki.squid-cache.org/SquidFaq/ContentAdaptation FWIW, Squid v3.3 has almost enough code to support this via a helper or even pure squid.conf magic, but I think we are missing response_header_add and possibly other small bits.
