[squid-users] %DST is waiting for domain lookup in external_acl_type

Hi everybody,
I am trying to use an external_acl_type to be able to filter internet
traffic according to specific User-agent headers and destination
(let's say you have the right to browse facebook only by using
Firefox).

this is my external acl:

external_acl_type getheaders %{User-Agent} %DST /etc/squid3/getheaders
acl myacl external getheaders
http_access allow myacl

this is my getheaders program:
(I runned it, and there are no permissions problem)

#!/bin/sh
read agent
read DST
date=`date`
echo "$date $agent" >> /var/log/squid3/headers.log
echo "$DST" >> /var/log/squid3/headers.log
echo "OK"
exit 1

and this is what I get in the debug when I try to access facebook:
2009/04/16 21:17:16.481| aclMatchExternal: acl="getheaders"
2009/04/16 21:17:16.481| aclMatchExternal:
getheaders("Mozilla/5.0%20...............0Version/4.0%20Safari/528.16
www.facebook.com") = lookup needed

of 'Mozilla/5.0%20(Macintosh...........0Safari/528.16
www.facebook.com' in 'getheaders' (ch=0x85a4760).

Apparently squid is waiting for a domain lookup that my getheaders
program should do.

I am a bit lost as I thought that the only reply options are OK/ERR

As I didn't find anything on google, if anybody has a clue, I would
appreciate the share! :-)

I am running the latest squid3 on debian

Thank you,
Julien
