Websense URL Filtering is not working in transparent proxy mode

[williamwong]

The "sh ip wccp web-cach detail" show that the redirection to CE cluster (5 of them)is working but the url filtering doesnt work at all. The Websense server is on the same VLAN as all the 5 CE. This thing happened when we reconfigured the wccp router list in all the 5 CE point to the msfc vlan ip from the loopback ip address of the msfc. But the strange thing is the filtering work well when we manually configured the proxy server in the internet explorer point to the CE. Any advise?

Thanks.

Problem is due to absense of Host header field . Most of the browsers will send host header field. But in HTTP/1.0 Host header is not a must , though most of the browsers send it.
