Please help me. Not possible because there is none that "recognize request protocol". What happens is admin configure squid.conf ports manually, one per protocol type to be recieved. Squid only supports HTTP, HTTPS, ICP, HTCP, and SNMP incoming traffic. The non-HTTP traffic support in Squid is for gatewaying traffic, where Squid makes the outbound connection in FTP/Gopher/HTTP/HTTPS/Wais/ etc so there is no detection or recognizing going on. Amos
