I am running into a problem when chaining 2 icap services. I tried configuring one of the services and that worked fine. The issue happens with specific sites.
For example, http://www.php.net/get/php-5.3.16.tar.bz2/from/a/mirror The error I get... The following error was encountered while trying to retrieve the URL: http://www.php.net/get/php-5.3.16.tar.bz2/from/a/mirror ICAP protocol error. The system returned: (100004) Unknown error 100004 This means that some aspect of the ICAP communication failed. Some possible problems are: The ICAP server is not reachable. An Illegal response was received from the ICAP server. My icap configuration is icap_enable on icap_send_client_ip on icap_send_client_username on icap_client_username_encode off icap_client_username_header X-Authenticated-User icap_preview_enable on icap_preview_size 1024 icap_service_failure_limit -1 icap_service_revival_delay 30 icap_service qlproxy1 reqmod_precache bypass=0 icap://127.0.0.1:1344/reqmod icap_service qlproxy2 respmod_precache bypass=0 icap://127.0.0.1:1344/respmod icap_service squidclamav1 reqmod_precache bypass=0 icap://127.0.0.1:1345/squidclamav icap_service squidclamav2 respmod_precache bypass=0 icap://127.0.0.1:1345/squidclamav adaptation_service_chain svcRequest qlproxy1 squidclamav1 adaptation_service_chain svcResponse qlproxy2 squidclamav2 adaptation_access svcRequest allow all adaptation_access svcResponse allow all Thanks in advance
