Hi, I'd like to allow websockets from specific domains through Squid in intercept sslbump mode. One of the clients reports: Firefox can’t establish a connection to the server at wss://ed1lncb62202.webex.com/direct?type=websocket&dtype=binary&rand=1602057495268&uuidtag=C99EG7B6-G550-43CG-AD72-7EA5F2CA80B0&gatewayip=X.X.X.X. This is what I have in my squid configuration: acl foreignProtocol squid_error ERR_PROTOCOL_UNKNOWN ERR_TOO_BIG acl serverTalksFirstProtocol squid_error ERR_REQUEST_START_TIMEOUT on_unsupported_protocol tunnel foreignProtocol on_unsupported_protocol tunnel serverTalksFirstProtocol on_unsupported_protocol respond all I am obviously not using on_unsupported_protocol properly. Any suggestions? Regards, Vieri _______________________________________________ squid-users mailing list squid-users@xxxxxxxxxxxxxxxxxxxxx http://lists.squid-cache.org/listinfo/squid-users
