Hi,
To sum up:

* accelerator, squid only speak to apache2 (originserver), no other
proxy speaking together.
* I want to weight loadblance the squid query to the parent (origin)
* + I want to filter the url in 2 type static and php. static
o URL are directed to the static peer, not balanced
o any php content URL are directed to php peer with weighted
round-robin selection.
squid behavior seems to be bugged when I put :
cache_peer php-01 parent 80 0 no-query originserver round-robin
weight=2 login=PASS
#cache_peer php-02 parent 80 0 no-query originserver round-robin
weight=0 login=PASS
cache_peer php-03 parent 80 0 no-query originserver round-robin
weight=2 login=PASS
cache_peer php-04 parent 80 0 no-query originserver round-robin
weight=1 login=PASS
cache_peer php-05 parent 80 0 no-query originserver round-robin
weight=2 login=PASS
cache_peer php-06 parent 80 0 no-query originserver round-robin
weight=2 login=PASS
cache_peer php-07 parent 80 0 no-query originserver round-robin
weight=3 login=PASS
cache_peer php-08 parent 80 0 no-query originserver round-robin
weight=2 login=PASS
weight are not respected and all the load seems to "fall" on the last
declared peer.

I tested the CARP config and squid complain about the conf syntax:
cache_peer php-01 parent 80 0 no-query no-digest originserver
login=PASS carp-load-factor=0.062500
The 2.6 STABLE 16 changed the cache_peer CARP directive. See
http://www.squid-cache.org/Versions/v2/2.6/squid-2.6.STABLE16-RELEASENOTES.html#s2
and http://www.squid-cache.org/Versions/v2/2.6/cfgman/cache_peer.html
carp_load_factor has been done away with, and now it seems you would
just replace "round-robin" in your config above with "carp".
