Hello, We have observed that on our system there is a link of dss1.siteadvisor.com generating background request and hence we were getting error in access.log file. Error was TCP_DENIED/400 error:invalid reuqest. Our proxy server is configured with authentication. When we enable transparent setting in http_port, the log was showing lots of request going to http://dss1.siteadvisor.com:3128/DSS/Ping? etc.. When we disable transparent it was showing error as mentioned above. I could not find out why squid generates such error. We stopped siteadvisor service on system and everything is fine. Any idea why squid generates such error? How to overcome from this?
