Redirecting URLs to your ProxySG appliance
You can add an action to your Symantec Messaging Gateway content filtering policies to redirect all browser requests to your Symantec Blue Coat ProxySG appliance. If a message triggers a verdict for the policy, the action adds the ProxySG URL to the beginning of every clickable URL in the message. When a user clicks a link, the computer redirects the browser request to the ProxySG URL. Your ProxySG policies then determine whether the user gets access to the linked webpage.
Your users' computers and browsers must be set up to communicate with the ProxySG appliance. In addition, you must define policies on ProxySG to evaluate and process the browser requests. The ProxySG default is to refuse access, so all redirected browser requests from SMG will fail until you define the relevant policies. For instructions on how to set up ProxySG policies, refer to the ProxySG documentation.
