The Resource Advisor (RAD) service on Security Gateways involves both the kernel and user space. Initially, URL lookups are performed in the kernel cache. If the URL is not found, the kernel module will notify the client about the miss and forward the asynchronous request to the RAD user space module, which is responsible for the online categorization. Thus, the RAD service operates with both kernel space for initial lookups and kernel cache management, and user space for processing online categorizations.

Therefore, the usermode core files would be located in the folder specified by $CPDIR.
