Hi all, I was testing Squid 3.0.PRE6-20070718 and the ICAP protocol was working fine. I've updated to 3.0.PRE7-20070919 and squid stop sending Respmod, although the Reqmod is ok, follow my conf: icap_service service_1 reqmod_precache 0 icap://127.0.0.1:1344/wwreqmod icap_service service_2 respmod_precache 0 icap://127.0.0.1:1344/wwrespmod icap_class filtro_url service_1 service_2 icap_access filtro_url allow all I've tracked the connection and I can see ICAP server answering his Methods: OPTIONS icap://127.0.0.1:1344/wwreqmod ICAP/1.0 Host: 127.0.0.1:1344 ICAP/1.0 200 OK Allow: 204 Encapsulated: null-body=0 ISTAG: "001-000-000003" Max-Connections: 50 Methods: REQMOD, RESPMOD, PROFILE, CERTVERIFY Options-TTL: 300 Preview: 30 Service: Webwasher 6.5.2.2676 (WW 6.5) Service-ID: ww Transfer-Preview: * X-Include: X-Authenticated-Groups,X-Authenticated-User,X-Client-IP Bugzilla?
