[squid-users] About squid ICAP implementation

Hi, would you tell me the ICAP implementation on squid.

- Question.1
  If there is no "icap_access" setting,
  The default icap access control is "allow" or "deny" ?
  It looks "allow"...

- Question.2
  Could we set "more than two" REQMOD icap servers (per request) ?

- Question.3
  squid "always" sends "Allow: 204" header to icap server, right ?
  If not, please tell me detail.

- Environment
  squid-3.0.STABLE10
