Why not show computer name in the log file when the client coming from a remote network?
If the client from a remote network, we can not ensure to get its computer name because there are routers and other network devices in the road, some information can not pass through them, and some information would become meaningless, such as MAC address. Moreover, we suggest you hide those information because retrieving them will take long time, decrease proxy perfomance, so if you do not care these information: computer name, MAC address, nt domain name, Hide them.
