Thanks a lot for your prompt response Christos, it worked. Another issue I am facing currently on the similar line is, when I am modifying the squid.conf file to have following entries:- icap_enable on icap_preview_enable off icap_send_client_ip off #icap_service s1 reqmod_precache 0 icap://172.16.43.39/reqmod icap_service s1 respmod_precache 0 icap://172.16.43.39/respmod icap_class c1 s1 acl HTTP proto HTTP acl GET method GET icap_access c1 allow HTTP GET Squid starts fine but while accessing any web page from the client it returns error saying "ICAP Protocol Error". "System returned [no error]" Possible ICAP communication failure?. Is there anything else I am missing here.
