[squid-users] problems using cache_peer_domain or urlpath_regex

hi there,

I am trying to set up a squid accelerator that shoul redirect using
cache peers.
my problem is, that what ever I do all request are grabbed by the first
peer.

I am using 2.6 stable 17 on a suse 10.3 box

these are the two different setups I was trying:

first attempt with cache_peer_domain
------------------------------------

cache_peer 127.0.0.1 parent 8480 0 no-query originserver name=server_11
cache_peer_domain server_11 www.hausbaumesse.ch

cache_peer 127.0.0.1 parent 9180 0 no-query originserver name=server_12
cache_peer_domain server_12 www.thoenssen.ch

this does not work at all, neither of the two peers can be reached

second attempt using urlpath_regex
----------------------------------
the VirtualHostBase in the regex is used since the urls are using an
apache rewrite rule of the form (all on one line):
RewriteRule /(.*)/$
http://127.0.0.1:3128/VirtualHostBase/http/www.hausbaumesse.ch:80/hausbauweb/hausbauweb/VirtualHostRoot/$1
[L,P]
the first peer catches them all even tough I use a "inpossible" pattern
with some XXX in it

cache_peer 127.0.0.1 parent 8480 0 no-query originserver name=server_11
acl path_server_11 urlpath_regex [-i]
^VirtualHostBase/http/XXXwww.hausbaumesse.ch
cache_peer_access server_11 allow path_server_11
cache_peer_access server_11 deny all

cache_peer 127.0.0.1 parent 9180 0 no-query originserver name=server_12
acl path_server_12 urlpath_regex [-i]
^VirtualHostBase/http/www.thoenssen.ch
cache_peer_access server_12 allow path_server_12
cache_peer_access server_12 deny all

I would be extremely gratefull for any pointers how to solve that.

thanks for your time
robert
