We have an ASA configured for WCCP, forwarding to a WSA in Transparent mode. HTTP traffic is blocked correctly per our policies. However, even though HTTPS Proxy is enabled with a root cert and Decryption Policy is set for global to Decrypt, the HTTPS traffic is not blocked and doesn't even show up in the reports. If we set the web browser manually to use the Ironport for proxy, it works. I thought the whole point of WCCP and transparent mode was to not have to define the proxy at the browser level?
