Squid3.0, ICAP server in python and respmod

Hey all,

After some tests, I made my mind for squid3.0 and python based ICAP server.
All works fine with reqmod precache but I cant' manage to get a response
modification.

On the side of the ICAP server, log messages display normally but on the
squid side no error is raised and the browser displays nothing (the
response body seems empty).

Note : I got a parent cache.
First of all my squidbox (and my ICAP server) is a debian etch with a
version 2.6.8-2-386 linux core.

Here is the squid.conf part about ICAP :
icap_enable on
icap_service s1 respmod_precache 0 icap://<icap server IP>:1344/respmod
icap_class c1 s1
acl images urlpath_regex \.jpg$
acl images urlpath_regex \.png$
acl images urlpath_regex \.gif$
acl images urlpath_regex \.ico$
icap_access c1 deny images
acl css urlpath_regex \.css$
icap_access c1 deny css
acl HTTP proto HTTP
acl GET method GET
icap_access c1 allow HTTP GET

Final note : all works perfectly without icap transformation.

All help will be greatly appreciated.
