Which two statements are true about the Websense redirect Web filter solution? ()(Choose two.)
A. The Websense redirect Web filter solution does not require a license on the SRX device.B. The Websense server provides the SRX device with a category for the URL and the SRX device then matches the category decides to permit or deny the URL.C. The Websense server provides the SRX device with a decision as to whether the SRX device permits or denies the URL.D. When the Websense server does not know the category of the URL, it sends a request back to the SRX device SurfControl server in the cloud.
