In CacheFlow version 3.4.x, the appliance requires that a license is installed in order to process traffic. If the appliance can access
https://device-services.es.bluecoat.com, the license will be downloaded and installed automatically the first time it boots, or with the CLI command, #license check-now. If the CacheFlow appliance is running 3.4.x and does not have a license, its traffic handling behavior is determined by the resource-overflow-action setting (either bypass or drop).
